WebA zymogen is an inactive precursor of an enzyme that must be cleaved or altered to form the active enzyme. The parietal cells secrete hydrochloric acid (HCl), which lowers the pH of the gastric juice (water + enzymes + acid). The HCl inactivates salivary amylase and catalyzes the conversion of pepsinogen to pepsin. WebJul 8, 2024 · The hydrochloric acid secreted in the stomach provides the optimum pH, which activates the pepsinogen enzyme required to digest proteins. Enzyme pepsinogen is …
