H+/k+ atpase proton pump
WebThe gastric H+,K+ ATPase--the gastric acid pump--is the molecular target for the class of antisecretory drugs called the proton-pump inhibitors (PPIs). These compounds- … WebSince these types of transporters are so costly in terms of energy, they are relatively rare. One other location for such an ATP pump is the proton/potassium exchanger (H+/K+ ATPase) found in the stomach. These proton pumps are responsible for creating the acidic environment of the stomach, and can cause acid reflux. Proton pump inhibitors like ...
