Intracellular fluid of a nerve cell contains both Na+ and K+ ions. Their concentrations are about 50 millimolar (mM) and 400 mM, respectively. But the extracellular fluid as those concentrations as 440 mM and 20 mM, respectively. Given that the electric potential inside the cell is -0.07V relative to the outside, calculate the Gibbs energy change for the transfer of 1 mole of each type of ion against the concentration gradient at 310 K.
