Proton Pump Function in Gastric Acid Secretion
The proton pump is an crucial component of gastric acid secretion. It's situated within the parietal cells lining the stomach. This enzyme, also known as H+/K+ ATPase, actively pumps protons (H+) from intracellular cytoplasm into the gastric lumen, producing the acidic environment necessary for digestion. Furthermore, the proton pump utilizes ATP
