Calculate the ΔG’° for the reaction between Cytochrome f (electron acceptor) and Ferrodoxin (electron donor). Cytochrome f (Fe3+) / Cytochrome f (Fe2+), E’°=0.365 V Ferredoxin (Fe3+) / Ferredoxin (Fe2+), E’°= -0.432 V Cytochrome b (Fe3+) / Cytochrome b (Fe2+), E’°= 0.077 V
Answer
ΔG’° = -nF ΔE’°= -1 x 96.5 x 0.797 = -76.9 kJ/mol
