Question Set
1. Why do some redox reactions in cells result in the transfer of electrons from a reductant with a higher standard redox potential to an oxidant with a lower standard redox potential?
(A): Electrons always go from reductants with high redox potentials to oxidants with low redox potentials
(B): None of the above
(C): Redox potentials are defined under standard conditions, and cellular conditions are typically not standard conditions
(D): The rules governing oxidation and reduction apply only in vitro, and not in vivo
