An investigation into the effect of temperature on the activity of the enzyme catalase found in potatoes. Aim: To investigate the effect of temperature on the activity of the enzyme catalase on the digestion of hydrogen peroxide. Prediction and scientific knowledge I predict that as the temperature is increased from 15 oC to 40 oC the activity of the enzyme the time taken for the enzyme to completely digest the hydrogen peroxide will increase. While at temperatures above 40 oC the activity will start to decrease as the temperature denatures the enzyme. Enzymes are biological molecules made of protein. Each enzyme has a specific substrate because the enzyme shape fits the shape of the substrate. The shape of the enzyme is held together by weak forces of attraction in the enzyme molecule. The way in which the enzyme works is called the 'lock and key' mechanism. The diagram below shows the lock and...
