Hi, just to add to the first answer. Enzymes are generally stored in these vessels called lysosomes. I'm not sure how much you would need to know about these. The enzymes will be synthesised in the rough endoplasmic reticum of the cells of the organs. These are then put into vessel called lysosomes and digestive enzymes will exit the cells via exocytosis. These will then serve to digest the food molecules (break down).
