IB Biology Sheran Gu Meghan Lena Nov. 15th Influence of pH on Enzyme Activities How does the pH of solution influence the speed of enzyme activities? Enzymes are protein catalysts and chemical that speed up chemical reaction without being involved in the reaction. They are involved in the human digestive system to help people digest food more efficient. Food are substrates to be break down and absorb through the digestive system in the body. Substrate is a molecule that bond with the active site

Determination of the Effect of pH on Amylase Activity Grace Chung Abstract: Amylase is an important enzyme in the human body as it allows for the consumption of starch by breaking the polysaccharide down into maltose units. All enzymes‚ including amylase‚ function best at a certain optimal pH. Therefore‚ in this experiment‚ the effect of different pHs on the reaction rate of amylase is studied. It was hypothesized that the amylase-starch reaction would proceed fastest at a pH closest to that of the

Determining the Optimal Temperature and PH of Barley Amylase Abstract The purpose of this experiment was to find the optimal temperature and pH of barley alpha-amylase. I hypothesize that the optimal temperature would be 55 degrees Celsius and the optimal pH would be 5.5. In this experiment‚ the starch is used as a substrate to examine the optimum temperature and pH for the reaction of alpha amylase. It is known that the measuring of disappearance (absorbance) of the substrate starch with iodine

However‚ when looking at the beliefs of a blind person‚ we discover that seeing may actually distort our beliefs. In Raymond Carver’s short story “Cathedral”‚ an unnamed narrator tells a story of meeting a blind man for the first time in his life. Before meeting Robert‚ the narrator tells us of how uncomfortable he is about him. If it had not been for his obligation

temperature on amylase activity Introduction Amylase is an enzyme that catalyses the breakdown of starch into sugars. Amylases are found in almost all plants‚ animals and microorganisms. Large amounts of amylase occur in germinating cereals‚ and in the pancreas and saliva of higher animals. Aim The aim of this experiment is to find out the rate of reaction between amylase and starch in a range of different reaction temperatures. Hypothesis As the reaction temperature of amylase solution

How Temperature Affects Amylase Activity Abstract This study of the effect of temperature on the enzyme amylase was performed to determine the relationship between the enzyme amylase and temperature. The rate of reaction was found to increase as the temperature of the environment was raised. As the temperature was raised from 5°C‚ 20°C‚ 35°C and finally to 80°C the rate of reaction followed this trend and also increased. However as predicted in the hypothesis of this experiment when the temperature

All we think about is scrubbing toilets or mopping floors‚ basically cleaning up after other people who most of the time show no appreciation. When asked what comes to mind when you hear the word janitor‚ some people would say someone who is poor and not well educated. Not very many

Amylase And Its Functionality At Various Ph Level Abstract Enzymes can be denatured at various ph levels in which then affects the shape of the enzymes structure and reactivity. The altering of shape causes substrates to not bind in the active site (Scott Freeman‚ Micheal Harrington‚ Joan. C Sharp‚ 2009). Amylase is used as a catalytic enzyme to determine the time period to convert starch into glucose monomers and transport into the bloodstream at different ph levels

These illusions are evident in the main characters of Iago‚ Michael Cassio and Othello. This review will discuss the illusion versus reality that is seen in the play. Illusion being judgements of an individual from what is seen from the outside‚ and reality being the truth and what is on the inside. This review will also discuss the various ways in which the theme of reality versus illusion are evident and how the value of the play Othello‚ is tied to its concern with the theme culminating in the

This article was particularly interesting to me‚ because I did not know that all organizations‚ clubs‚ and teams at Universities experience hazing. Honestly‚ when I think of hazing‚ the first thing that comes to my mind is some sort of greek affiliation. When I attended Paul Quinn College‚ a HBCU in Dallas‚ Texas
