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

Figure: Energy transformation in coupled fluxes, J, and forces, F and Ξp, 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 to the negative compartment (from Gnaiger 2014).
