Title: “The Effect of Substrate Concentration‚ Enzyme Concentration‚ pH and Temperature on Enzyme Activity” Abstract: In the following experiments we will measure precise amounts of potato extract as well as Phenylthiourea‚ combined with or without deionized water and in some instances change the temperature and observe and record the reaction. We will also investigate the different levels of prepared pH on varying samples of the potato extract and the Phenylthiourea and record the results.

Biology Digestive Enzyme Experiment “Design an experiment in which you will investigate a digestive enzyme’s effect on digestion” Research Question: To determine the effect of enzyme concentration on the rate of digestion. This will be done by increasing the concentration of the enzyme diastase and investigate its effect on the rate of starch digestion. The rate will be determined by the amount of time it takes to completely digest the powdered starch‚ the complete digestion will be indicated by

Activity of the Enzyme Catalase in breaking down Hydrogen Peroxide and the effect of various factors on Enzyme Activity Introduction The enzyme catalase is present in cells in order to speed the breakdown of hydrogen peroxide (H2O2)‚ which is a toxic chemical to the human body. When hydrogen peroxide is broken down‚ the end products are Water (H2O) and Oxygen (O2). In this report‚ the reaction of catalase to hydrogen peroxide is being tested. Furthermore‚ the effects of temperature‚ concentration

Effect of pH on Enzyme Activity A piece of Solanum tuberosum (potato) was removed and mixed with distilled water in a blender. The resulting solution was filtered through multiple layers of cheese cloth to filter out the liquid by eliminating any large pieces in the solution. The solution created was catechol. Five different solutions were prepared as blanks with each test tube containing 6.0mL of a different pH (pH 4‚ pH6‚ pH7‚ pH8‚ pH10) of phosphate buffer‚ 1.0mL of the enzyme and 1.0mL of water
