Dipeptides into amino acids are are converted through_____________?
Correct answer: B. Erypsin
- A. Amino peptidase
- B. Erypsin
- C. Pepsin
- D. Trypsin
Explanation
Erepsin is a mixture of intestinal peptidases that breaks dipeptides into amino acids at the intestinal surface. Pepsin acts mainly on proteins in the stomach and trypsin acts mainly on proteins or large peptides in the small intestine, so students may choose trypsin because it is also a pancreatic protein-digesting enzyme.
