... same time allowance so the enzyme and substrate have the same amount of time in each experiment to react. I will test each temperature three times thus making anonymous readings prominent. I will wash out all apparatus after use to prevent cross contamination. I will make sure the potatoes are cut to the same size so there is the same amount of surface for the substrate to react with. I will use a new batch of 50mlsof hydrogen peroxide each time. I will make sure that the pH conditions are the same each time (pH 7). In this experiment I am choosing to explore one of the factors that effect enzyme activity. I am aware that there are also other factors, which I will have to monitor to make sure the experiment is fair. Preliminary: I know that factors such as temperature, pH levels, and substrate concentration effect enzyme activity that ...
