Aim: I am trying to find out what happens if I change the surface area of a potato cylinder and whether or not the amount of oxygen produced by the enzyme catalase changes. Prediction: I predict that the larger the surface area of the potato cylinder, the more oxygen there is produced. The scientific evidence that supports my prediction is because there is more surface areas, there are more enzymes so therefore more active sites. The active sites are what produce the oxygen so the more active sites exposed the more oxygen there is produced. Information about enzymes! What are enzymes? Enzymes are biological catalysts. They speed up chemical reactions in all living things, and allow them to occur more easily. They occur in plant cells and animal cells. Without them we would not be alive. Enzymes are proteins. They are very important substances because they control the chemical reactions that happen in...
