Jan 3, 2018. The parietal cells secrete H , at a pH as low as 0.8, into the gastric lumen by primary active transport involving carriers that function as an ATPase. The bicarbonate ion is produced within the parietal cell by the dissociation of carbonic acid, formed from CO2 and H2O by the enzyme carbonic anhydrase.

. the processes of membrane fusion and endocytosis. Protons transported to the canalicular lumen are joined by electrically balancing Cl- ions* and osmotically drawn water, all together constituting isotonic hydrochloric acid (~0.15N HCl) which drains through the lumen of each gastric gland into the cavity of the stomach.

Since this enzyme produces and uses protons and bicarbonate ions, carbonic anhydrase plays a key role in the regulation of pH and fluid balance in different parts of our body. In our stomach lining it plays a role in secreting acid, while the same enzyme helps to make pancreatic juices alkaline and our saliva neutral.

Gastrine is the only peptide hormone released from the stomach which mediates gastric acid secretion, with a well established. in a histamin depended way, gastrine is the main mediator of gastric acid secretion. Acetylcholine is. gastric secretion in dogs by carbonic anhydrase inhibitor 2-acetylamino-1,3,4-thiadiazol- 5-.

Epithelial cells in pancreatic ducts are the source of the bicarbonate and water secreted by the pancreas. Bicarbonate is a base and critical to neutralizing the acid.

Virtually complete inhibition of carbonic anhydrase in isolated gastric mucosa leads to inhibition of acid secretion and damage to the cells indistinguishable from that occurring when acid secretion is stimulated by histamine in the absence of external supplies of carbon dioxide. A similar inhibition of carbonic anhydrase in.
