What Factors Affect How Fast Enzymes Work? For this investigation, I will be finding out how the temperature affects the rate of reaction in enzymes. The enzyme I will be testing is Amylase, which breaks down starch molecules into sugar molecules. All enzymes are proteins; they have an active site, which the substrate (which in this case is starch) fits into. The more you heat an enzyme, the quicker it works. This is because heat gives molecules energy so they work faster. They move around quicker and are more likely to bump into each other. At temperatures above 60°c, the enzyme structure will begin to fall apart. It denatures, and the active site disappears. When this happens, the enzyme will not function at all. The temperature at which the reaction works fastest is called the optimum temperature. For most enzymes in the human body, this is around 40°c. Other factors like...
