Oxidative phosphorylation

Description

[[Description:: Oxidative phosphorylation (OXPHOS) is the oxidation of reduced substrates with electron transfer to oxygen, 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

Energy transformation in coupled fluxes, J, and forces, F and Δp, of oxidative phosphorylation. 2[H] indicates the reduced hydrogen equivalents of CHO substrates and electron transfer to oxygen. J_H⁺out is coupled output flux. Proton leaks dissipate energy of trans-located protons from low pH in the positive P-phase to the negative N-phase (Gnaiger 2012 MitoPathways).
