Meaning of the standard reduction potential:When compound loses an e- (serves as a reductant),the structure left behind becomes capable of acceptingan e- (serves as an oxidant).cytochrome b(Fe++)+cytochrome c(Fe+++)cytochrome b(Fe+++)+cytochrome c(Fe++)Reductant XOxidant YOxidant X’ Reductant Y’Reductant X and Oxidant X’ are termed a REDOX PAIR!Electrons flow from the redox pair with the morenegative E 0 to the more positive E 0 .
