Temperature, Amylase and Starch Introduction Enzymes are the catalysts of chemical reactions taking place in living organisms. Each Enzyme is a protein that catalysts a particular reaction. Enzymes break down bigger molecules into smaller ones. Enzymes work best at temperatures like body temperature (37?C). They also work best within a small PH range, which is different for each enzyme. Amylase occurs widely in plants and animals. In human it is found in the Salvia and in pancreatic juice. Like most enzymes temperatures above 60?C denature amylase. Amylase helps to break up starch by the following: Starch ? Amylase ?Glucose Enzymes like amylase break starch in the following way: - Enzymes have a special shape called the active site into which the molecule can fit. If you increase the temperature the active site changes. So at a certain point the starch will not fit into the active site. We say that the enzyme has been denatured. From research we...
