The Proton Pump: Its Role In Photosynthesis And Survival
WebbMechanism of action. The proton pump (H+ /K + -ATPase) is the final common pathway for acid secretion in gastric parietal cells, and inhibition of the pump blocks acid secretion almost completely (see Fig. 33.1 ). Proton pump inhibitors are pro-drugs that are rapidly absorbed from the small intestine. WebbFor both of these reasons, protons flow in spontaneously, from the P side to the N side; the available free energy is used to synthesize ATP (see below). For this reason, PMF is defined for proton import, which is spontaneous. PMF for proton export, i.e., proton pumping as catalyzed by the coupling sites, is simply the negative of PMF(import). portland condos zillow
