Answer:
B. In the small intestine, carboxypeptidase attacks peptide bonds.
E. Pepsin causes the hydrolysis of some of the peptide bonds in proteins.
Explanation:
The digestion of protiens doesn't occur in mouth, it occurs at only 2 locations in GIT :
- In the stomach
- In the small intestine
Digestion of protiens start in stomach causing the stimulation of gatrin hormoone which stimulates the release of gastric juice containing HCl , Pepsinogen , Rennin (in infants). The pepsinogen is activated to pepsin by HCL and pepsin itslef, and cause hydrolysis of the peptide bonds in the protiens.
The remainder of protien digestion occurs in small intestine as a result of the action of enzymes including trypsin and peptidases. Carboxypeptidases attack the peptide bonds and result in cleavage.
