WebbSuccinate-driven reverse electron transport (RET) is one of the main sources of mitochondrial reactive oxygen species (mtROS) in ischemia-reperfusion injury. RET is dependent on mitochondrial membrane potential (Δψ m) and transmembrane pH difference (ΔpH), components of the proton motive force (pmf); a decrease in Δψ m and WebbDuring oxidative phosphorylation, the proton motive force that is generated by electron transport is used to: A) create a pore in the inner mitochondrial membrane. B) generate the substrates (ADP and Pi) for the ATP synthase. C) induce a conformational change in the ATP synthase. D) oxidize NADH to NAD+. E) reduce O2 to H2O. 14.
