Intestinal epithelial cells pump glucose into the cell against its concentration gradient using the Na+Na+glucose symporter. Recall that the Na+Na+ concentration is significantly higher outside the cell than inside the cell. The symporter couples the "downhill" transport of two Na+Na+ ions into the cell to the "uphill" transport of glucose into the cell.

If the Na+Na+ concentration outside the cell ([Na+]out)([Na+]out) is 147 mM147 mM and that inside the cell ([Na+]in)([Na+]in) is 17.0 mM,17.0 mM, and the cell potential is 54.0 mV54.0 mV (inside negative), calculate the maximum energy available for pumping a mole of glucose into the cell. Assume the temperature is 37 C.
