An investigation to determine the effect of temperature on the effectiveness of catalase Aim The aim of this experiment is to determine how the rate and efficiency of the enzyme catalase is affected by change in temperature. Prediction From what I know about enzymes and their properties, the catalase will work best at approximately 37°C, will denature at higher temperatures, and work slower or not at all in low temperatures, however I do not know the extent of the effect or the temperatures at which denaturing occurs for catalase. Preliminary work As preliminary work for the investigation we have performed a number of tests to determine optimum conditions for obtaining results. The first experiment used a 1cm3 piece of potato, which contains some catalase, and 10ml of hydrogen peroxide. However we found that the reaction did not occur fast enough, and not enough gas was given off to accurately measure. We found that liver was much...
