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