Enzymes are those proteins which participate in a chemical reaction without being consumed in the reaction. These enzymes work as a catalyst which speed up the rate of the chemical reaction. The enzyme is responsible for converting the substrate into a product. Pepsin is an enzyme present in the stomach it is activated by hydrochloric acid it is a peptic enzyme which converts proteins into peptones, trypsin and chymotrypsin are the enzymes secreted by the pancreas and it is responsible for digestion of proteins.
