Answer:
(B). H⁺/K⁺ ATPase.
Explanation:
H⁺/K⁺ ATPase (or hydrogen-potassium pump) is a proton pump, present in parietal cells of stomach. The main function of hydrogen-potassium pump is to acidify the contents of stomach and to activate pepsin (a digestive enzyme).
It helps in gastric acid formation releasing hydrogen ions to the lumen with exchange of potassium ions.
Gastric acid reflux represents a condition, in which stomach acid comes up to the esophagus from stomach. Hence, one way to treat gastric acid reflux is to inhibit H⁺/K⁺ ATPase that would decrease synthesis of gastric acid in stomach.
Thus, the correct answer is option (B).
When you exercise, your body releases chemicals called endorphins. These endorphins interact with the receptors in your brain that reduce your perception of pain. Endorphins also trigger a positive feeling in the body, similar to that of morphine.
