BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Pepsin Pearls 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: -The function of pepsin in gastric digestion is to break down proteins into smaller fragments of polypeptides.

Detailed explanation-3: -An enzyme made in the stomach that breaks down proteins in food during digestion.

Detailed explanation-4: -Pepsin is a proteolytic enzyme, secreted as its precursor pepsinogen by chief cell of gastric pits of vertebrate stomach. It gets activated due to the acid (HCl) present in the stomach. It converts proteins into polypeptides.
