I will measure the volume of gas produced as the catalase in the potato tissue reacts with the hydrogen peroxide to create water and oxygen. I will change the temperature at which the reaction takes place, but to make the test a fair one I will keep the pH level on the solution, the amount and concentration of the solution, and the area and the volume of the potato the same. I will have to take into account the concentration of Catalase in the potato, is this cannot be controlled. Catalase is an enzyme. The purpose of an enzyme is...
of gas escaping or a few seconds difference in the time. Another problem was that I had to conduct the experiment over several days to I was unable to use the same potato and therefore there was a different concentration of catalase in the potatoes. If I was to carry out the experiment again then I would

However I think the evidence I obtained is enough to support the predictions I had made. There are however some anomalous results in the graph and these are at 5 and 2?é??C and I have circled these on the graph.
