Choose all the true statements about protein digestion and hydrolysis.
A. The chemical digestion of proteins begins in the mouth with the process of mastication.
B. In the small intestine, carboxypeptidase attacks peptide bonds.
C. Free amino acids are passively absorbed through the intestinal wall.
D. Pancreatic juices are more acidic than gastric juices.
E. Pepsin causes the hydrolysis of some of the peptide bonds in proteins.

A, B, C and E

Explanation:

A. The moment food mixes with saliva in the mouth when chewing, chemical digestion starts, because saliva contains enzymes that breaks down carbohydrates.

C. Free amino acids can either take passive or active transport system, thus it can be absorbed through intestinal wall.

E. Pepsin acts as a catalyst to the hydrolysis of the peptide bond. The reaction enables the process of digestion by breaking down the protein into smaller pieces.

B. Carboxyperptidase attacks or cleave the peptide bonds, also Trypsin do attacks or cleave the peptide bonds.

However,

D. Pancreatic Juice are more alkaline in nature, while gastric juice are more acidic in nature.

answer: oof wait

explanation:

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
