PROTON PUMP FUNCTION IN GASTRIC ACID SECRETION

The proton pump contributes a critical role for gastric acid {secretion|. The pump is an integral membrane protein situated on the apical surface of parietal cells within the stomach lining. It catalyzes the active movement of protons (H+) from the cytoplasm of parietal cells into the gastric lumen, leading to the acidification of the stomach conte
