The cytochrome bc complexes are critical components of electron transfer chains in mitochondria, chloroplasts and many bacteria. They act by coupling the oxidation of quinol species to vectoral proton pumping across bioenergetic membranes, contributing to the proton motive force required for ATP synthesis. Certain physiological conditions and inhibitors of the mitochondrial cytochrome bc1 complex can induce these complexes to generate superoxide (Muller 2002), making them important subjects for oxidative stress research.
