Which enzyme released by the gastric glands helps digest proteins in the stomach?
Pepsin
The gastric glands in the stomach lining secrete gastric juice, which contains hydrochloric acid and the enzyme pepsinogen.
Hydrochloric acid converts inactive pepsinogen into active pepsin.
Pepsin breaks down proteins present in food into smaller peptides in the acidic environment of the stomach.
Maltase, lipase and amylase act on carbohydrates and fats at other stages of digestion, not primarily in the stomach on proteins.
Hence, pepsin is the gastric enzyme that digests proteins in the stomach.
