Calculate the standard free energy change associated with reduction of cytochrome c by NADH.Write down the different steps of your calculation.

½ O2 + 2H+ + 2e- --> H2O   = +0.82

Succinate + CO2 + 2e- --> alfa-ketoglutarate    = -0,67

Balanced rxn: ½O2 + 2H+ + 2e- --> 2H2O   = +0.82

So full = ½O2 + 2H+ + succinate + CO2 --> 2H2O   + alfa-ketoglutarate

$∆$G°= -nF$∆E_0$

(-2 * 96.48kj/molV * +0.82) – (-2*96.48kj/molV* -0.67)

=  -158.2272 – 129.2832 = -287.5104kj/mol
