Lab 6.C Hypothesis: If enzyme activity is affected by the pH of a solution‚ then the enzymes will experience the greatest activity at a pH of 6. Variables: Independent Variables Dependent Variable Controls Four different pH values (10‚ 7‚ 6‚ and 3) Change in color of the solution The amount of potato extract‚ pH solution‚ and catechol used (1 cm +/- .1cm) Size of the test tubes Amount of time allowed for the catechol to sit with the potato extract and pH solution (20 minutes with 5

Aim: To investigate the effect of hydrogen peroxide concentration on enzyme catalase Indroduction: Enzymes are proteins. They function as biological catalysts. They lower the energy barrier of a reaction so that the reaction can take place at body temperature. Also‚ they can speed up Metabolic reactions without being changed or used up. During a reaction‚ an enzyme molecule combines temporarily with the substrate. When the reaction is complete‚ the enzyme molecules returns to its original dorm

The Effect of the Changes in the Environment to the Functionality of the Enzymes Introduction a. Background In our everyday lives‚ enzymes are used in our bodies‚ and in nature around us‚ to speed up the chemical reactions happening constantly‚ which happens by lowering the amount of activation energy needed to start various reactions. The way this works is by attaching the particular substrate to the active site of the enzyme‚ where it will start to aid the chemical reaction. Then‚ the allosteric

Thesis: There are more costs as a result of Charlie’s experiment It is clear that there are more cost that weighs out the benefits of Charlie’s experiment. To start with‚ everyone needs to have a friend to make life more enjoyful and to share their important parts of their lives. But‚ after the surgery people would look at Charlie as if he wasn’t human at all. He had no one to share his experience being smart. In the story it said‚“All the rest demanded that I be fired.

Stanley Milgram Experiment The video I watched was a reenactment of the original Stanley Milgram experiment conducted by Derren Brown. In the experiment‚ the subjects were told that they were doing an experiment on how punishment could affect learning. They were tricked into thinking that they picked their own roles when they actually got the teacher roles and the actor got the learner role on purpose. They started the experiment by showing them what they were going to do to the “learner”. They were

Was the Milgram Experiment Ethical or Valid? In 1961‚ Stanley Milgram‚ a psychologist at Yale University‚ conducted an experiment on a group’s obedience to authority. This experiment has encountered intense scrutiny ever since its findings were first published in 1963; many people question the ethics and validity of the experiment. Multitudes of researchers have taken it upon themselves to determine the answers to the questions (McLeod). Based on new guidelines for ethics‚ Stanley Milgram’s experiment

EXPERIMENT 3: IDENTIFICATION OF FOOD CONSTITUENTS IN MILK. INTRODUCTION: In this experiment two milk samples are given and its compositions are tested using different methods such as using benedict solution to test the presence of reducing sugar‚ using copper II sulphate to test the presence of protein‚ using K3( to test the presence of fat. However in this experiment‚ not only are the milk tested for its composition‚ the amount of the particular substance such as reducing sugar‚ protein and

Enzyme kinetics (catalase/kmno4) Enzyme catalysis Farah Mohamed galal 22-3014 t09 Introduction: E + S → ES → E + P Enzymes are proteins which act as a catalyst in biochemical reactions(affect the rate of achemical reaction). The substrate binds to the active site of the enzyme. Any deformation of the active site will affect the activity of the enzyme‚ these are some ways that enzyme action may be affected because of them: 1- Salt concentration: If it is close to zero or very high
Premium Catalysis Enzyme Catalase
Introduction Enzymes are proteins produced by living organisms to speed up the rate in which chemical reactions occur. This process can happen fast‚ slowly‚ or stop the chemical reaction all together depending on the temperature‚ pH and concentration. Catalase is one of the most common enzymes. It is found in living organisms and is used to break down hydrogen peroxide. This must happen because hydrogen peroxide is considered toxic to cells in the body. However‚ when catalase is used it breaks
