The Effects on Enzymes By Bailey Rose The Effects on Enzymes Bailey Rose 10/31/2011 Abstract In this lab exercise‚ the study of enzyme catalase‚ we viewed the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase from starch and measure the rate of activity under different conditions. Changes in temperature and pH along with Substrate Concentration and Enzyme Concentration were the conditions tested in the experiment. Our class performed

Aim: To investigate the effect of skin sensitivity in response to cold temperature in different parts of the body by timing the maximum amount of time in which ice-pack can be held to that area. Hypothesis: If the layer of skin is relatively thin‚ the nerve response to cold will be the fastest‚ increasing the skin’s sensitivity. This therefore means that the fastest responses to cold will be in the face‚ and specifically the nose. The skin consists of 3 main layers; the epidermis‚ dermis and

Enzyme Catalase Activity in Reaction with the Substrate Hydrogen Peroxide Abstract We performed these experiments to observe the effects of enzymes on the rate of reactions. We tested and compared the activity of the enzyme catalase on the substrate H2O2 in various states and percentages‚ and observed the absorption values of the enzyme-substrate relationship at different concentrations. Our results show that the more substrate available‚ the quicker the reaction will happen except in one test
