Digestive enzymes are released in inactive forms called zymogens. This is necessary to prevent the digestive enzymes from digesting the cells that produce them. In a zymogen, a peptide blocks the active site of the enzyme.Cleaving off this peptide activates the enzyme.igestive enzymes are released in inactive forms called zymogens.
