GASTRIC PARIETAL CELL FUNCTION: THE ROLE OF THE H+-K+ ATPASE PUMP

Parietal cells within the gastric mucosa play a crucial role in digestion by secreting hydrochloric acid (HCl). This potent acid environment/medium/solution is essential for protein denaturation, activating digestive enzymes, and killing harmful bacteria ingested with food. The key mechanism underlying HCl secretion involves the intricate H+-K+ ATP
