In the mitochondrial electron transfer chain, one of the steps that mediates transfer of electrons from nadh to o2 is the transfer of electrons from the reduced (ferrous) heme of cytochrome b to the oxidized (ferric) heme of cytochrome c1: fe ii (cyt b) + fe iii (cyt c1) → fe iii (cyt b) + fe ii (cyt c1) the standard state reduction potentials of fe iii (cyt c1) and fe iii (cyt b) are 0.25 v and 0.08 v, respectively, relative to the standard hydrogen electrode.(a) express the above redox reaction as two half reactions, one as an oxidation and one as a reduction. (b) determine the equilibrium constant for the reaction as written. is this reaction spontaneous, favoring products?
