The 2 half reactions of the reaction of interest is given in question. The reaction of interest that takes place in pyruvate dehydrogenase complex is the transfer of 2 electrons and 2 H+ from dihydrolipoamide to FAD and the reaction is given below.
Dihydrolipoamide + FAD Lipoamide + FADH2
First we need to find change in standard reduction potential value () of the above reaction.
Here the electron acceptor is FAD whose E'0 value is given as -0.01 V and the electron donor is Dihydrolipoamide whose E'0 is given as -0.29 V . E'0 is the standard reduction potential value of reduction half reaction of species; it is represented as in question.
