Oxidative phosphorylation

Description

P.jpg Oxidative phosphorylation (OXPHOS) is the oxidation of reduced fuel substrates by electron transfer to oxygen, chemiosmotically coupled to the phosphorylation of ADP to ATP and accompanied by an intrinsically uncoupled component of respiration. The OXPHOS state (P) of respiration provides a measure of OXPHOS capacity, which is frequently corrected for residual oxygen consumption (ROX).

Abbreviation: OXPHOS

Reference: Gnaiger 2014 MitoPathways


MitoPedia methods: Respirometry 


MitoPedia topics: "Respiratory state" is not in the list (Enzyme, Medium, Inhibitor, Substrate and metabolite, Uncoupler, Sample preparation, Permeabilization agent, EAGLE, MitoGlobal Organizations, MitoGlobal Centres, ...) of allowed values for the "MitoPedia topic" property.

Energy transformation in coupled fluxes, J, and forces, F and Ξ”p, of oxidative phosphorylation. 2[H] indicates the reduced hydrogen equivalents of CHO fuel substrates and electron transfer to oxygen. JH+out is coupled output flux. Proton leaks dissipate energy of translocated protons from low pH in the positive P-phase to the negative N-phase (Gnaiger 2014 MitoPathways).
