The oxidative phosphorylation electron transport chain (OXPHOS-ETC) of the inner
mitochondrial membrane is composed of five large protein complexes, named CI–CV. These …

Many, if not most, redox reactions are coupled to proton transfers. This includes most
common sources of chemical potential energy, from the bioenergetic processes that power …

The review describes four flavin-containing cytoplasmatic multienzyme complexes from
anaerobic bacteria and archaea that catalyze the reduction of the low potential ferredoxin by …

Cytochrome b 6 f (cytb 6 f) lies at the heart of the light-dependent reactions of oxygenic
photosynthesis, where it serves as a link between photosystem II (PSII) and photosystem I …

Anaerobic ammonium-oxidizing (anammox) bacteria primarily grow by the oxidation of
ammonium coupled to nitrite reduction, using CO2 as the sole carbon source. Although they …

In the final steps of energy conservation in aerobic organisms, free energy from electron
transfer through the respiratory chain is transduced into a proton electrochemical gradient …

The mitochondrial respiratory chain is a major source of reactive oxygen species (ROS) in
eukaryotic cells. Mitochondrial ROS production associated with a dysfunction of respiratory …

This review focuses on key components of respiratory and photosynthetic energy-
transduction systems: the cytochrome bc 1 and b 6 f (Cyt bc 1/b 6 f) membranous …

ROS (superoxide and oxygen peroxide in this paper) play a dual role as signalling
molecules and strong oxidizing agents leading to oxidative stress. Their production mainly …

Apart from complex I (NADH: ubiquinone oxidoreductase) the mitochondrial cytochrome bc
1 complex (complex III; ubiquinol: cytochrome c oxidoreductase) has been identified as the …
