Question
What is the energy requirement to transport 2 mol of K* across the
membrane by the Nat-K+ ATPase transporter protein at 37 °C under
conditions in which the membrane potential is 70 mV (the inside of the cell is
negative relative to the outside) and the ion concentrations are as follows:
[K+]outside = 5 mM
[K+Jinside = 140 mM
[Na loutside = 150 mM
[Na+Jinside = 10 mM
+1.83 kJ
+ 3.66 kJ
O-1.83 kJ
O-3.66 kJ
