PROTON PUMP FUNCTION IN GASTRIC ACID SECRETION

Proton Pump Function in Gastric Acid Secretion

The proton pump plays a critical role in gastric acid {secretion|. The pump is an integral membrane protein situated at the apical side of parietal cells within the stomach lining. It facilitates the active transport of protons (H+) from the cytoplasm of parietal cells into the gastric lumen, ultimately to the lowering of the stomach contents. Th
