Explanation:
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: -Pepsin is activated by a low pH (1.5 to 2). Pepsin works best at a pH of 1.8, which is very acidic. Pepsin, the stomach protease, is usually thought to have little action at pH 4.
