The Limits of Amylase Essay Abstract This report explains the purpose of this experiment in a way that conveys information to the reader about Amylase’s ability to withstand acidic or basic pH. To do this, two test tubes were both filled with 5mL of a 5% amylase solution. The first one was filled with an acid, while the other was filled with a base. After dropping liquid Iodine and Benedict’s solution into each one, the tube with a basic pH tested positive for glucose. The acidic solution tested (mostly) negative for glucose, although there were trace amounts at the bottom. Overall, my conclusion is that only acidic solutions inhibit Amylase’s ability to digest starch. Background The goal of the experiment is to test whether or not Amylase can withstand abnormal changes in pH without denaturing itself. Salivary Amylase is an enzyme that acts upon any polysaccharide that enters the mouth (mainly starch). However, it has a few other clinical uses. It is used for the diagnosis of acute pancreatitis, an inflammation of the pancreas, and other medical conditions regarding Amylase levels in the body. Amylase’s first discovery in 1831 led to new experiments about this enzyme. By separating pancreatic Amylase from Trypsin, they were able to realize that it acted upon starch, breaking it down into a simple sugar, or monosaccharide. In the diagram (featured below), the active site of this enzyme contain three major acidic groups. These contain a calcium ion (the large gray sphere) , the chloride ion (the large green sphere), and the chain of five sugar units (in yellow orange). Previously mentioned, this enzyme will act upon starch and break it down into simple sugars. 2 Hypothesis If we expose Amylase to a variety of acidic and basic solutions to test whether it will still digest starch or not, then I think that it will denature both ways, because Amylase is normally intolerable to any pH above 8 or below 6. Materials and Procedures The following will be useful in this experiment: 20mL of a 5% Amylase solution 20mL of a 1% starch solution 8 test tubes At least 5mL of HCl At least 5mL of NaOH Hot plate Beaker full of water (for incubation) Liquid Iodine Solution Benedict’s Solution Follow this procedure: 1. In your first 4 test tubes, add the following solutions accordingly to each tube: -Test tube 1: 5mL of distilled water -Test tube 2: 5mL of the 5% Amylase solution -Test tube 3: 5mL of Amylase solution + 2-3 drops of HCl -Test tube 4: 5mL of Amylase solution + 2-3 drops of NaOH 2. Add 5mL of the starch solution into each tube. 3. Incubate each tube in the beaker of water for 30 minutes. The temperature should be 37 °C (98.6 °F). 4. After incubation, split half of all contents in each tube into 4 new tubes. 5. Insert 2-3 drops of the Iodine solution into the first set of beakers (the original 4). Then, insert 2-3 drops of the Benedicts solution into the second set of test tubes. 6. Record any color changes. 3 Results The first test tube (containing distilled water) was light brown when mixed with iodine, and blue when mixed with Benedict’s solution. The second test tube (5% Amylase solution) was light brown when mixed with iodine. It became orange when Benedict’s was added to the mix. The third test tube turned dark brown when the iodine was added. The other beaker with test tube 3’s contents remained blue when Benedict’s solution was added, although traces of Orange were found. The last test tube appeared Light Brown with the iodine mixed in (3 drops are always used), and appeared Orange when combined with the Benedict’s solution. Discussion Many of the test tubes ended up looking like I expected them to, except the fourth beaker. I had not expected that Amylase, under the influence of a very basic solution, could still act as a catalyst for starch. With a pH of  9 or higher, Amylase would normally denature itself. This could mean one of two things: Amylase is capable of functioning normally under a very high pH, or it could’ve been human error that led to this surprising result. To minimize chances of this happening again, assuming that this was human error only, would be to maximize the pH in the fourth beaker to 14 instead of 12, should a new lab arise, focusing on Amylase’s ability to withstand a high pH without getting denatured. Conclusion Overall, most of my results agreed with my notes and background knowledge about Amylase, apart from the difference in test tube 4. Like I predicted, the Amylase solution (tube 2) tested positive for simple sugars, the acidic solution denatured the enzyme, and the distilled water did absolutely nothing. Sources Dugdale, D.

INTRODUCTION: Every cells of living organism contains genetic materials known as deoxyribonucleic acid, DNA. It can be isolated from tissue sample of living things by separating it from other cellular component in a manner that still preserves its structures. The structure of DNA is double-stranded helices that made up from the monomer of nucleotides. Each of the nucleotides composed of three parts that are the phosphate group, deoxyribose sugar backbone and also nitrogenous bases (Adenine, Guanine, Thymine and Cytosine). This nitrogenous base are arranged in sequence and holds the information and coding for controlling the physical trait that we all have as well as the regulation of our body. DNA extraction is simply a process that results in separation of DNA from the cells or viruses that are hosting it. Through the meaning is simple but the process is not. When we go into the peculiar details of DNA extraction, we realize that it’s more of an initial stage in other intensive DNA testing processes. DNA test could be performed for any reason; however for any DNA testing to happen the first stage normally is the isolation and extraction of DNA molecules from the cells that they reside in. DNA extraction follows a series of step, stripping all proteins from the DNA and the extraction protocols have to make sure that the DNA thus obtained via isolation and extraction is of high or acceptable quality. DNA isolation is a process of purification of DNA from sample using a combination of physical and chemical methods. Currently it is a routine procedure in molecular biology or forensic analysis. Primary structure consists of linear sequence of nucleotides that are linked together by phospodiester bonds. It is the linear sequence of nucleotides that make up the primary structure of DNA. Specific techniques must be chosen for isolation of DNA from some samples such as samples from microorganisms with thick cellular wall, for example yeast. Biological DNA represents the information which directs the functions of a living thing. A.

Result : Table C(i) : Orange DNA Extraction Table C (ii) : Apple DNA Extraction RESULT ALL OF EXPERIMENTS: Sample Extraction Amount Apple Success Large Onion Success Small Orange Success Small Yeast Success Small DISCUSSION: Based on our experiment discussion, we obtained that the difference amount of DNA extraction from yeast, onion, apple and orange is different. The amount of apple DNA extraction is larger than onion, orange and apple DNA extraction. Each step of the process will help in a certain way to extract DNA, until we are finally successful in the end. In the yeast, extraction, the ethanol will be able to separate the DNA and it will float between the less dense ethanol and the denser homogenizing mixture. In the onion DNA extraction, the chloroform and homogenizing medium will help break down the cell membranes and the ethanol like in the yeast DNA extraction. It will cause the DNA to separate and be suspended in the interface between the two solutions. It will be same to apple and orange DNA extraction. The precaution step on this experiments we tilt 45Â º to add the ethanol. This is because it will form a layer on top of the sample because the ethanol is less than water. So, it does will be on the top of layer. We also used 50ï‚ ° of hot water in yeast solution. Its will formed the best of result because hot water is the optimum temperature for yeast. We also obtained about perceptions step why only clear solution produced in these experiments. Its means the extraction was failed. CONCLUSION: REFERENCES: http://www.whatisdna.net/dna-extraction.html http://classic.sidwell.edu/us/science/vlb5/Labs/DNA_Extraction_Lab/dna_extraction_lab.html#predictions http://sciencehk.weebly.com/lab-reports.html ANSWER AND QUESTION: Answer all the questions. 1. Describe the functions of following: a. Applying blender to sample and salt/detergent solutions Strain the DNA mixture. b. Salt Salty water helps the DNA precipitate (solidify and appear) when alcohol is added. c. Detergent Detergents are used to break down cell walls and nuclear membranes to release the DNA. They work by chemically poking holes in the cell membranes or walls. Once holes are poked in the membranes, the membranes can be further distrupted mechanically, as with a blander. After that, it’s easier to get the contents of the cell out, including the DNA, d. Meat tenderizer solutions Meat tenderizer acts as an enzyme. The DNA in the nucleus of the cell is moulded, folded, and protected by proteins. The meat tenderizer cuts the proteins away from the DNA. e. 95% ice cold ethanol Having ice cold ethanol only increases the rate of precipitation of DNA and helps increase yield of DNA. It can either use room temp or ice cold ethanol for DNA precipitation. Think about precipitation of a super concentrated solution as you decrease the temperature. As the temperature decreases, the amount of precipitation increases. Overall temperature affects solubility. As temperature decreases the substance becomes more insoluble (in general. this does not apply to every molecule). So, ice cold EtOH allows for more DNA to interact together and allow for a more rapid and efficient precipitation of DNA. 2. Compare the reliability amount of DNA obtained from all the samples. The reliability amount of DNA obtained from apple is much larger compared to Reliability amount of DNA from onion, orange and apple. 3. Write out the principle involved in DNA extraction. – Break open cells by mashing the fruit. – Dissolve organelles and cell membranes with detergent. – Separate DNA from proteins with salt – Filter out the clumps with a coffee filter – DNA precipitates in cold alcohol and is spooled out.

Different Aspects of Women

In Bram Stoker’s novel, Dracula, Stoker portrays many different aspects of women’s roles in the nineteenth century. Women had a strictly defined role within the era; there was no thought of equality, no thought that women could liberate themselves sexually. Stoker uses women in this novel to critique against women’s liberation. Stoker’s portrayal of women makes the novel seem like a fantasy. Women are primarily objects of delicate beauty who occasionally need to be rescued from danger. In the novel Mina Murray is the embodiment of Victorian virtue in which she is loyal, earnest, innocent, and dependent of her husband.Stoker creates another character, Lucy Westenra who is completely opposite of Mina. Lucy is embodies the desire of women who want to liberate themselves. Only Mina shows any considerable strength or resourcefulness. Lucy is primarily two-dimensional victim, picture of perfection who is easy for Dracula to prey upon. Mina is not most noteworthy for her physical beauty like Lucy. Mina’s sexuality remains mysterious throughout the whole novel of Dracula. Even though she gets married, she never gives voice to anything resembling a sexual desire or impulse, which enables her to retain her purity.Stoker creates suspense about whether Mina will be lost like Lucy. Throughout the novel, Mina portrays what women are expected to do in the society. In the beginning of the novel, Lucy is much like Mina. She is a paragon of virtue and innocence, qualities that brings three suitors to her. Lucy differs from Mina in one aspect, she shows her sexuality. Lucy’s physical appearance captivates each of her suitors, and she displays comfort or playfulness about her desirability that Mina never feels.Stoker amplifies this faint whisper of Lucy’s insatiability to a monstrous volume when he describes the undead Lucy as a wonton creature of ravenous sexual appetite. With Stoker’s concern with female chastity and virtue , it is hard to imagine him granting his female characters the degree of sexual freedom. Lucy’s wounds suggest a virgin’s first sexual encounter. She escapes into the night and is penetrated in a way that makes her bleed. â€Å"As she looked, her eyes blazed with unholy light, and the face became wreathed with a voluptuous smile†¦She still advanced, however, and with a anguorous, voluptuous grace, said: ‘Come to me, Arthur. Leave these others and come to me. My arms are hungry for you. Come, and we can rest together. Come, my husband, come! ’ There was something diabolically sweet in her tones— something of the tingling of glass when struck— which rang through the brains even of us who heard the words addressed to another† ( Stoker 227). This threat becomes reality as Lucy, now a blood and sex starved vampire, does her best to lure her fiance into eternal damnation.Lucy is the first to fall under Dracula’s spell because she displays comfort or playfulness about her desirability that Mina does not show. Stoker also describes her as the â€Å"loose† woman, she isn’t conservative as Mina and she loves all the attention from her suitors. Lucy also falls under Dracula’s spell because Dracula has this charm that attracts Lucy making her have strong desire for Dracula. Lucy shows that she has sex appeal and that she has desirability for men; and it made her an easy target for Dracula, knowing she will give in when he approaches her.

Free Essays on The House Of Seven Gables

â€Å"The sympathy or magnetism among human beings is more subtle and universal than we think; it exists, indeed, among different classes of organized life, and vibrates from one to another. Loosely based on the events of Hawthorne’s own life, The House of the Seven Gables attempts to show the suffering of descendants forced to repent for the sins of their â€Å"father†, while they are unknowingly renewing the curse by nurturing the ancestral greed that has passed through the generations. Thus the various themes of the novel reflect the central idea of continued sin through the greed and guilt of a declining family. Each generation struggles to escape the sins of the past, only to be thrust forcefully back to face the offenses of their forefathers. The House of the Seven Gables is a tale of loneliness and greed caused by the sin of preceding generations. The opening of the novel is set in puritan times during the Salem witch hunts. The villainous Colonel Pyncheon wrongly accused the innocent Matthew Maule of witchcraft so that the Maule land would fall into the Pyncheon family’s hands. Upon his death, Maule â€Å"addressed [Colonel Pyncheon] from the scaffold, and uttered a prophecy...God will give him blood to drink". The physical wrongdoing of Colonel Pyncheon against Matthew Maule was avenged at the former’s death, with the curse being fulfilled. However, the essence of the crime lived on through the generations. By chapter two, the focus of the novel has shifted to the modern generations of the Pyncheon family. The family has severely declined since the Colonel’s time, yet the curse of greed is as strong as ever. The remains of the family consist of a decrepit spinster named Hepzibah, now the caretaker of the house of the seven gables; her insane brother Clifford, who was just recently released from prison; their devilish cousin Judge Jeffrey, a man fixated upon his own greed; and their distant...

Content and Function Words in English

Content and Function Words in English Each word in English belongs to one of the eight parts of speech. Each word is also either a content word  or a function word. Lets think about what these two types mean: Content Words vs. Function Words Content information, meaningFunction necessary words for grammar In other words, content words give us the most important information while function words are used to stitch those words together. Content Word Types Content words are usually nouns, verbs, adjectives, and adverbs. A noun tells us which object, a verb tells us about the action happening, or the state. Adjectives give us details about objects and people and adverbs tell us how, when or where something is done. Nouns, verbs, adjectives and adverbs give us important information required for understanding. Noun person, place or thingVerb action, stateAdjective describes an object, person, place or thingAdverb tells us how, where or when something happens Examples: Nouns Verbs house enjoy computer purchase student visit lake understand Peter believe science look forward to Adjectives Adverbs heavy slowly difficult carefully careful sometimes expensive thoughtfully soft often fast suddenly Other Content Words While nouns, verbs, adjectives and adverbs are the most important content words, there are a few other words that are also key to understanding. These include negatives like no, not and never; demonstrative pronouns including this, that, these and those;  and question words like what, where, when, how and why. Function Word Types Function words help us connect important information. Function words are important for understanding, but they add little meaning beyond defining the relationship between two words. Function words include auxiliary verbs, prepositions, articles, conjunctions, and pronouns. Auxiliary verbs are used to establish the tense, prepositions show relationships in time and space, articles show us something that is specific or one of many, and pronouns refer to other nouns. Auxiliary verbs do, be, have (help with conjugation of tense)Prepositions show relationships in time and spaceArticles used to indicate specific or non-specific nounsConjunctions words that connectPronouns refer to other nouns Examples: Auxiliary Verbs Prepositions do in has at will though is over has been between did under    Articles Conjunctions Pronouns a and I an but you the for him so us since ours as she Knowing the difference between content and functions words is important because content words are stressed in conversation in English. Function words are non-stressed. In other words, function words are not emphasized in speech, while content words are highlighted. Knowing the difference between content and function words can help you in understanding, and, most importantly, in pronunciation skills. Exercise Decide which words are function and content words in the following sentences. Mary has lived in England for ten years.Hes going to fly to Chicago next week.I dont understand this chapter of the book.The children will be swimming in the ocean this time next week.John had eaten lunch before his colleague arrived.The best time to study is early in the morning or late in the evening.The trees along the river are beginning to blossom.Our friends called us yesterday and asked if wed like to visit them next month.Youll be happy to know that shes decided to take the position.I wont give away your secret. Check your answers below: Exercise Answers Content words are in bold.

Social Meaning of Vampires Essay Example | Topics and Well Written Essays - 750 words

Social Meaning of Vampires - Essay Example Eighteenth century can be bestowed with the credit for promoting the vampire phenomena after tons of vampire superstitions flew into Western Europe. However, it was Bram stoker’s vampire novel by the name of Dracula that greatly popularized the modern vampire superstition. When questioned about the image of Vampires or Dracula to be more precise, plentiful of people will be of the opinion that Vampires are nothing but tall, dark and handsome men dressed in a long white or black cape and have blood flowing out of their mouths like a river. Others think that Vampires are young, gorgeous, sensual and young women who seduce people, men mostly, in their beds at night and then succeed to suck their blood. This wide realm of opinions proves the very noticeable fact that the social meaning of vampires and the cultural meaning of vampires significantly fluctuate from one area to the other, one region to the other and one continent to the other. To begin with, in ancient Babylonia, people faithfully believed that there existed a female vampire popularly known as Lilu and Lilu was seen feeding and nourishing the pregnant women and at times the newborn babies in that region. On the other hand, in Slavic regions, the residents of that area believed that vampires took birth due to a collection of reasons and some of those reasons were offensive burial rituals and practices and dying an â€Å"unnatural death. (Vampires: The Origin of the Myth by Adrian Nicholas McGrath) In this increasingly modernizing world, as science and technology advances with every passing second, several cultural interpretations exist revolving around vampires. Various cultures and societies place unique concentration and even more distinctive interpretation to these deadly creatures. However, there exists an overlapping section where one can find some of
