Plant Structure 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? The rules governing oxidation and reduction apply only in vitro, and not in vivo Electrons always go from reductants with high redox potentials to oxidants with low redox potentials None of these Redox potentials are defined under standard conditions, and cellular conditions are typically not standard conditions The rules governing oxidation and reduction apply only in vitro, and not in vivo Electrons always go from reductants with high redox potentials to oxidants with low redox potentials None of these Redox potentials are defined under standard conditions, and cellular conditions are typically not standard conditions ANSWER DOWNLOAD EXAMIANS APP
