Each enzyme is specific as it has a certain job to do, for example, the enzyme pepsin is a protease, and it breaks proteins down to polypeptides. Catalase is an enzyme found in all living plant and animal cells. Hydrogen peroxide is a toxic substance made in the cells of our liver as a by-product, and if not removed immediately it can be quite harmful.
