Protein digestion begins in the stomach under the influence of pepsinogen; it continues in the duodenal lumen under the influence of pancreatic proteolytic enzymes; and it is completed intracellularly in the small intestinal brush border.

Question

Quizplus · Accepted Answer

This statement is true. Protein digestion starts in the stomach with the help of pepsinogen, a precursor of pepsin, and then continues in the small intestine with the help of pancreatic proteolytic enzymes such as trypsin, chymotrypsin, and carboxypeptidase. The final stages of protein digestion occur at the brush border of enterocytes in the small intestine.
