Q

describe what occurs inside a parietal cell to produce HCl

  • water dissociates
  • hydroxyl ions combine with CO2 with the help of carbonic anhydrase to produce bicarbonate which moves out into interstitial fluid
  • HCO3 moving out allows Cl to move in
  • H ions pumped out into lumen in exchange for K ions, creating electrical gradient which transports Cl out into lumen
