In dog skeletal muscle, the extracellular and intracellular concentration of Na+ are 150 mM and 12 mM, and those of K+ are 2.7 mM and 140 mM, respectively. Calculate the total free energy change as 3 Na+ are transported out and 2 K+ are transported in by the Na+-K+ pump. Assume that the temperature is 25°C and the membrane potential is –60 mV. Give your answer in kJ/mol to 1 decimal place.
