Oxidative phosphorylation

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.

Abbreviation: OXPHOS

Reference: Gnaiger 2012 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.
