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 located on the apical membrane of parietal cells in the stomach lining. It facilitates the active passage of protons (H+) from the cytoplasm of parietal cells into the gastric lumen, resulting to the acidification of the stomach contents. T
