PROTON PUMP FUNCTION IN GASTRIC ACID SECRETION

The proton pump is an crucial component of gastric acid secretion. It's positioned within the parietal cells lining its stomach. This enzyme, also known as H+/K+ ATPase, actively moves protons (H+) from the cytoplasm into the gastric lumen, generating the acidic environment necessary for digestion. Furthermore, the proton pump utilizes ATP as an
