![O Att
Intestinal epithelial cells pump glucose into the cell against its concentration gradient using the Nat-glucose symporter. Recall
that the Nat concentration is significantly higher outside the cell than inside the cell. The symporter couples the "downhill"
transport of two Nat ions into the cell to the "uphill" transport of glucose into the cell.
If the Nat concentration outside the cell ([Na lout) is 161 mM and that inside the cell ([Na* Jm) is 17.0 mM, and the cell
potential is -50.0 mV (inside negative), calculate the maximum energy available for pumping a mole of glucose into the cell.
Assume the temperature is 37 °C.
