A chemical which stimulates the secretion of pepsin is :
- (A)Anti histamine
- (B)Cimetidine
- (C)Histamine✓ Correct
- (D)Zantac
Answer: (C)
Solution
Histamine is a chemical messenger that stimulates the secretion of pepsin and hydrochloric acid (HCl) in the stomach. It acts on H₂ receptors in the gastric parietal cells to promote acid secretion. Antihistamines like cimetidine and Zantac (ranitidine) are H₂ receptor antagonists that block histamine's action and reduce acid secretion.
