Effects of pH on the Function of Enzymes Rena Mototani Glen Rock High School Advanced Biology 2014-2015 Effects of pH on the Function of Catalase Rena Mototani Problem: How does the pH of a cell affect the function of the enzyme catalase? Introduction In this lab‚ we experimented the effects of pH on the function of the enzyme catalase. Catalase is an enzyme that brings about the reaction by which hydrogen peroxide is decomposed to water and oxygen (Encyclopedia Britannica). The

Project Enzymes are organic catalysts produced by living organisms which aid in the progression of specific biochemical reactions without undergoing any permanent chemical changes themselves. They are complex‚ conjugated proteins necessary and required to sustain life. Today‚ enzymes are also used world-wide in a variety of different industrial applications such as the production of paper‚ wine fermentation‚ and bio-remediation. One of the most important industrial applications enzymes are used

Email: femijohn@gmail.com 43 INTRODUCTION The roles of metal ions in metalloenzymes include direct participation in catalysis‚ stabilization of protein structure and regulation of enzymatic activity. Membrane alkaline phosphatase (ALP) is a metal-containing enzyme that serves as a good model for the study of metal ion interactions in enzyme catalysis. Native E. coli ALP contains three

Break Break Break by Alfred Lord Tennyson The poem ‘Break Break Break’ by Alfred lord Tennyson was written in 1834‚ the year after the death of one of his closest friends; Arthur Henry Hallam. Hallam and Tennyson had been very close for almost six years‚ and Hallam had been engaged to Tennyson’s sister‚ so his fatal brain hemorrhage in 1833 came as a great shock to Lord Tennyson. Hallam’s death affected him so much that nineteen years later he named his son Hallam.The literate subject of the poem

Lipids are organic compounds which consist of hydrogen oxygen and carbon. When fatty acids are combined together‚ they form lipids. The energy storage lipids‚ tri-glycerides‚ are formed when three fatty acids and bonded together with a molecule of glycerol. The energy for this process is usually undertaken by the body‚ which will bond together fatty acids and glycerol in order to make tri-glycerides for energy storage in the form of fat. They release more energy per unit mass than carbohydrates

Why do policemen break the law? A Case study of Police Constable Tsui Po-ko Introduction The role of policeman is very important. Policemen help to prevent and detect crime in the society‚ so that we can have a safe and stable society. If a policeman commits crime‚ the public will lose trust towards the police. It will influence the public order in the society. This paper aims to analyze the causes and factors which contributed to the commission of serious crime by policemen in Hong Kong through

difficult to assess why people break the law. Although this process may be difficult‚ it is not without merit. In this paper I will discuss my personal opinion on crime causation and how my life experiences have shaped these views. I believe this process is important because one must always be aware of their attitudes and biases when critically examining social phenomena. I believe that there are three levels in one’s life that can increase his or her likelihood to break the law. On the macro level

Procedures for Part A: For Activity A‚ we first tested enzyme activity. First‚ we used an H2O2 syringe to transfer 10 mL of H2O2 into an unlabeled 60-mL cup. Then‚ we used a transfer pipet to add one mL of catalase solution into the unlabeled 60-mL cup that we put H2O2 in. After that‚ we observed the solution for one minute. Then we tested the effect of boiling on enzyme activity. First we used a transfer pipet to transfer 4 mL of catalase into a test tube. After that‚ we placed the test tube filled
