THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen.

Detailed explanation-2: -A protease (also called a peptidase, proteinase, or proteolytic enzyme) is an enzyme that catalyzes (increases reaction rate or “speeds up") proteolysis, breaking down proteins into smaller polypeptides or single amino acids, and spurring the formation of new protein products.

Detailed explanation-3: -Protease along with trypsin hydrolyze peptide bonds. Hence, enzymes that break down proteins in the food are pepsin, trypsin, chymotrypsin, carboxypeptidase, dipeptidase, etc.
