Can someone please help me answer the questions above and explain why did you pick that answer?

Thanks

The F_1/F_0 ATP synthase is a transporter of In the P-type transporters, the large conformation change in protein structure that causes ion transport across the membrane occurs What is the free energy change generated by the transport of 1 mole of Na+ from a concentration of 0.143 M to 0.005 M with a transmembrane potential of -0.050mV (Same direction as transport direction)? T =37 degree C, F = 96,500 J/mol V.

Explanation / Answer

Question no 3.

The amount of free energy released or consumed can be calculated from the equation

dG = (RT/z) ln (Xi/Xo)

Xi = concentration of ion inside the membrane

Xo = Concentration of ion outside the membrane

z= charge of ion

So, dG = (8.314 J.mol-1.K-1) (310 K/1) ln 0.005/0.143

= -8.6 kJ/mol
