Macmillan Learning Intestinal epithelial cells pump glucose into the cell against its concentration gradient using the Nat-glucose symporter. The symporter couples the "downhill" transport of two Na+ ions into the cell to the "uphill" transport of glucose into the cell. If the Nat concentration outside the cell is 143 mM and that inside the cell is 17.0 mM, and the membrane potential is -50.0 mV, what is the maximum energy available for pumping a mole of glucose into the cell? Assume the temperature is 37 °C. AGgluc 9.6 x10³ Incorrect kJ mol- What is the maximum ratio of [glucose]in to [glucose Jout that could theoretically be produced if the energy coupling were 100% efficient? 3.0 x 10³ 0.883 3.3 x 10-4 8.00
