Gastric juice is made up of substances secreted from parietal cells, chief cells, and mucous-secreting cells. The cells secrete HCI, proteolytic enzyme zymogens, mucin, and intrinsic factor. The pH of gastric juice is acidic, between 1-3. If the pH of gastric juice is 2.4. what is the amount of energy (AG) required for the transport of hydrogen ions from a cell (internal pH of 7.4) into the stomach lumen? Assume that the potential difference across the membrane separating the cell and the interior of the stomach is -60.0 mV (inside of cells negative relative to the lumen of the stomach). Assume that the temperature is 37 degree C. The Faraday constant is 96.5 kJ- V^-1- mol^-1 and the gas constant is 8.314times 10^-3 kJ middot mol^-1 K^-1. Express your answer in kJ/mol.
