...e substances at 37.5̊C due to the fact that in the previous experiment, this was found to be the optimum temperature that catalase reacts at. It was because of this constant that I used the set of data of the catalase at 37.5̊C from the first experiment to provide a neutral environment for the experiment. The way in which the data was collected for the first experiment was identical to that needed to be done by the second. From this data, it was determined that the neutral environment for the catalase had the best results, which makes it clear that when the enzyme is in a pH of the opposite extremes such as basic or acidic, it is un able to function properly. When it is too basic then the enzyme will become inactive and when the enzyme is too acidic then the enzyme will denature, both rendering it unable to function at its optimum efficiency that all enzymes need.
