Aim To investigate the effect of changing the total surface area of a potato containing catalase, on the enzyme activity when hydrogen peroxide is added. Background Information An enzyme is a biological catalyst, which is present in potatoes. Hydrogen peroxide is produced in all living cells. If it builds up, it is toxic and so it must be broken down in order to prevent this. Catalase is an enzyme found in all living cells. It speeds up the breakdown of hydrogen peroxide into two harmless substances, water and oxygen. The enzyme that I am using, catalase, is found in potatoes. It exists inside the cells and is released when the potato is cut open. Because it is from the potato, it is normally in a cold place when the potato is growing. Correcting pH or temperature imbalances will usually allow the enzyme to resume its original shape or conformation. Some substances...
