Question
What is the energy requirement to transport 3 mol of Na+ 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]outside = 150 mM [Na]inside = 10 mM O-41.22 kJ + 13.74 kJ +41.22 kJ O-13.74 kJ

Expert Solution
Step 1

As we see in the above question that the ion concentration difference of K+ from out side to inside is 135 mV and of Na+ is 140 mV. 

 

The membrane potential is at the resting membrane potential which is 70 mV at normal temperature.
