Each electron from cytochrome c is donated to a Cu redox center in Complex IV. The Ɛ°′ value for the CuA redox center is 0.245 V. Calculate ΔG°′ for this electron transfer. (Express your answer in kJ/mol and be sure to use the correct number of significant digits!)
____kJ/mol
Homework Answers
n = number of electrons transferred = 1
F = faraday = 96500 C
ΔG°′ = - n F Eo
= - 1 x 96.5 x 0.245
= - 23.6 kJ / mol
