Mitochondrial respiration, an important bioenergetic process, relies on operation of four
membranous enzymatic complexes linked functionally by mobile, freely diffusible elements …

The dimeric cytochrome bc1 complex catalyzes the oxidation–reduction of quinol and
quinone at sites located in opposite sides of the membrane in which it resides. We review …

The redox states of exogenously added ubiquinone-2 and cytochrome c, and the
protonmotive force (delta p) of rat liver mitochondria were measured as the respiration rate …

Mitochondrial respiratory supercomplexes, comprising complexes I, III, and IV, are the
minimal functional units of the electron transport chain. Assembling the individual complexes …

The cytochrome bc 1 complex is a fundamental component of the energy conversion
machinery of respiratory and photosynthetic electron transfer chains. The multi-subunit …

Enzymes of the bc 1 complex family power the biosphere through their central role in
respiration and photosynthesis. These enzymes couple the oxidation of quinol molecules by …

The cytochrome bc complexes found in mitochondria, chloroplasts and many bacteria play
critical roles in their respective electron transport chains. The quinol oxidase (Q o) site in this …

The cytochrome bc 1 and related complexes are essential energy-conserving components
of mitochondrial and bacterial electron transport chains. They orchestrate a complex …

The cytochrome bc1 complex catalyzes electron transfer from ubiquinol to cytochrome c by a
protonmotive Q cycle mechanism in which electron transfer is linked to proton translocation …

In eukaryotic cells, mitochondria perform cellular respiration through a series of redox
reactions ultimately reducing molecular oxygen to water. The system responsible for this …
