22 The standard reduction potentials (E'°) for the following half reactions are given.

If you mixed succinate, fumarate, FAD, and FADH2 together, all at I M concentrations and in the presence of succinate dehydrogenase, which of the following would happen initially?
(A) Fumarate and succinate would become oxidized; FAD and FADH2 would become reduced.
(B) Fumarate would become reduced; FADH2 would become oxidized.
(C) No reaction would occur because all reactants and products are already at their standard concentrations.
(D) Succinate would become oxidized; FAD would become reduced.
(E) Succinate would become oxidized; FADH2 would be unchanged because it is a cofactor.
