PROTON PUMP FUNCTION IN GASTRIC ACID SECRETION

The proton pump plays a critical role during gastric acid {secretion|. The pump is an integral membrane protein found on the apical surface of parietal cells within the stomach lining. It facilitates the active passage of protons (H+) from the cytoplasm of parietal cells into the gastric lumen, leading to the lowering of the stomach contents. Thi
