What is a zymogen giving reference to an example?
A zymogen is the inactive form of an enzyme. For instance the enzyme pepsinogen is produced by chief cells in the gastric pits. Pepsinogen is a zymogen. Hydrochloric acid produced by the parietal cells of the gastric pit work to cleave a peptide bond forming pepsin, which can now work to digest proteins in the stomach.
