25/8/2018В В· This study also points to novel aspects of mitochondrial respiratory controls and electron transfer complexes as possible targets of AhR. In this study, we show that BaP treatment not only inhibits mitochondrial oxygen consumption, but also affects mitochondrial DNA content and electron transport chain complexes. It has been shown that coenzyme Q can facilitate electron transport through the membrane of cells for the NADH-ferri-reductases (Oakhill et al., 2008). This schematic proposes a method of how this can occur, based upon the mechanisms of coenzyme Q electron shuttling within complex I and II of the electron transport chain.

Complex V is a multisubunit transmembrane protein complex that couples the energy liberated from electron transport to the terminal electron acceptor Mitochondrial ATP and O 2 −• /H 2 O 2 are intimately linked by electron transfer from nutrients to di-oxygen (O (GSSG), which is the result of the enzyme-mediated oxidation of two Gibbs Free Energy . Changes of both enthalpy (ΔH) and entropy (ΔS) combined decide how favorable a reaction is. For instance, burning a piece of wood releases energy (exothermic, favorable) and results in a substance with less structure (CO 2 and H 2 O gas, both of which are less 'ordered' than solid wood).

Transplasma membrane electron transport (tPMET) systems transfer electrons across the plasma membrane, resulting in the net reduction of extracellular oxidants (e.g., ferricyanide) at the expense of intracellular reductants such as NADH and ascorbate.

Description of enzyme-mediated reactions, succinate is formed from the conversion of succinyl coenzyme A and then oxidized to fumarate by succinate dehydrogenase (SDH), or complex II of the electron transport chain, transferring electrons to power ATP synthase (Figure1) [4,13]. Succinate can also be generated
