The cytochromes are heme‑containing proteins that function as electron carriers in the mitochondria. Calculate the difference in

the reduction potential (ΔE∘′) and the change in the standard free energy (ΔG∘′) when the electron flow is from the carrier with the lower reduction potential to the higher. cytochrome c1 (Fe3+)+e−↽−−⇀cytochrome c1 (Fe2+)E∘′=0.22 V cytochrome c (Fe3+)+e−↽−−⇀cytochrome c (Fe2+)E∘′=0.254 V Calculate ΔE∘′ and ΔG∘′ . ΔE∘′= V ΔG∘′= kJ/mol

Answer:

DeltaG0 = -(1) X 96485 X 0.034 = -3280.49 J /mole = -3.281 KJ / mole

Explanation:

E0cell = E0cathode - E0anode

the cathode will be with more reduction potential and anode will have low reduction potential

E0cell = 0.254 - 0.220 = 0.034 V

Now

DeltaG0 = -nFE0cell

E0cell = 0.034 V

F = 96485 C

n = 1

Putting values

DeltaG0 = -(1) X 96485 X 0.034 = -3280.49 J /mole = -3.281 KJ / mole
