When TMPD/ascorbate is added to mitochondria as a source of electrons (TMPD/ascorbate reduce cytochrome c directly) oxygen is reduced to H2O by the electron transport chain (ETC).(a) Approximately how many ATPs would result per O2 consumed when electrons come from TMPD/ascorbate? (b) If dinitrophenol (DNP) is added to the mitochondria in (a) above, what effect would DNP have on the yield of ATPs per O2 reduced from TMPD/ascorbate electrons?
