Mitochondrial coenzyme Q (mtQ) of the inner mitochondrial membrane is a redox
active mobile carrier in the respiratory chain that transfers electrons between
reducing dehydrogenases and oxidizing pathway(s). mtQ is also involved in
mitochondrial reactive oxygen species (mtROS) formation through the mitochondrial
respiratory chain. Some mtQ-binding sites related to the respiratory chain can
directly form the superoxide anion from semiubiquinone radicals. On the other
hand, reduced mtQ (ubiquinol, mtQH
