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. Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach. A low pH (1.5 to 2) activates pepsin.

Detailed explanation-2: -Protease (made in the pancreas; breaks down proteins)

Detailed explanation-3: -Specificity: Pepsin hydrolyzes peptide bonds between large hydrophobic amino acid residues, whereas trypsin hydrolyzes peptide bonds at the C-terminal side of lysine or arginine. Function: Pepsin acts on proteins and converts them into peptones, while trypsin converts peptones into polypeptides.
