Question

Explain the digestion of protein in stomach

Answer 1

Pepsin is the active protein-digesting enzyme of the stomach. Pepsin acts on protein molecules by breaking the peptide bonds that hold the molecules together. Digestion of protein is completed in the small intestine by the pancreatic enzymes trypsin, chymotrypsin, and carboxypeptidase.

Answer 2

protein digetion occurs in the stomach and duodenum in which 3 main enzymes, pepsin secreted by the stomach and trypsin and chymotrypsin secreted by the pancreas, break down food protein into polypeptides that are then broken down by various exopeptidases and dipeptidases into amino acids.
