How temperature effects the breakdown of hydrogen peroxide by the enzyme catalase Aim: To investigate the effect of temperature on catalase An enzyme is a protein molecule that speeds up chemical reactions in all living things, without enzymes these reactions would be to slow or would not happen. Enzymes are also useful because they cannot be used up and does not affect the reaction in any other way. My experiment will be testing the affect of temperature on catalase. I will need to try and keep these constant for the experiment to be fair: 1. PH: if the pH is too high or too low the enzymes will become denatured because of the loss of H+ ions at too high PH, and the gain of H+ ions when the pH is low. 2. Concentration of enzyme: The higher the concentration, the more successful collisions occur and the higher the rate of reaction. I will...
