14. Calculate AG for the reaction catalyzed by Na, K ATPase that expels 3 Na* outside in exchange for 2 K* coming inside. Assume actual AG for ATP hydrolysis -50 kJ/mol, membrane potential on the cell membrane 70 mV (negative inside), K* 140 mM in, 4 mM out, Na* 12 mM in, 145 mM out, temperature is 37C.
