Catalase Design Experiment Aim To determine what effect pH has on the rate of reaction in the presence of the enzyme catalyse. Observing the enzyme activity on potato rods will discover this. The amount of carbon dioxide produced indicates the rate of reaction. Hypothesis The enzyme will have an optimum pH of around neutral. Either side of the optimum pH will have relatively high rates of reaction and far away from the optimum pH will have a low rate of reaction. The enzyme catalase is found in many tissues including potato and liver. It is important because it breaks down the hydrogen peroxide formed in metabolism. Hydrogen peroxide is toxic and if it were not broken down it would kill the cells. As it does this, it liberates carbon dioxide that can be collected. 2H2O2 2H2O + O2 Variables Constants * Volume of buffer solution (3cm³) - controlled because different values will affect the reaction...
