Gastric Acid Secretion in Parietal cells: Mechanism
Key player: H+/K+ ATPase or “proton pump” (in canalicular membrane of parietal cells) a. Hydrogen ions are generated within the parietal cell from dissociation of water. The hydroxyl ions formed in this process rapidly combine with carbon dioxide to form bicarbonate ion, a reaction catalyzed by carbonic anhydrase. b. Bicarbonate…
