Question

Quizplus · Accepted Answer

Protein digestion is completed in the small intestine by the action of peptidases, which break down peptides into individual amino acids for absorption into the bloodstream. Pepsin is involved in breaking down proteins in the stomach, but its action is incomplete and needs to be continued in the small intestine. The pancreas secretes enzymes like trypsin, which also help to break down proteins in the small intestine, but the main site of protein digestion and absorption is the small intestine. The colon is not involved in protein digestion.
