PROTON PUMP FUNCTION IN GASTRIC ACID SECRETION

The proton pump functions a critical role in gastric acid {secretion|. The pump is an integral membrane protein found at the apical side 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 neutralization of the stomach contents. T
