What is the general function of digestive enzymes? Involves breaking down large, insoluble molecules into small, soluble ones. Enzymatic reaction is known as digestion and this is defined as the chemical breakdown of the ingested complex food molecules by the action of biological enzymes, into simplest form that can be absorbed into the blood stream and assimilated into living cells.
