Quizplus · Accepted Answer

The initial digestion of protein occurs in the stomach and is catalyzed by the enzyme pepsin. Pepsin is secreted by the chief cells in the stomach and helps to break down proteins into smaller peptides. Chymotrypsin and trypsin are enzymes that are secreted by the pancreas and continue the process of protein digestion in the small intestine. Peptidase is a general term for any enzyme that breaks down peptides, but it is not specific to the initial digestion of protein. Amylase is an enzyme that breaks down carbohydrates, not proteins.
