Question

Gastric juice is made up of substancessecreted from parietal cells, chief cells, and mucous-secretingcells. The cells secrete HCl, proteolytic enzyme zymogens, mucin,and intrinsic factor. The pH of gastric juice is acidic, between1-3. If the pH of gastric juice is 1.1, what is the amount ofenergy (?G) required for the transport of hydrogen ions from a cell(internal pH of 7.4) into the stomach lumen? Assume that thepotential difference across the membrane separating the cell andthe interior of the stomach is
