 Context examples 

Mutation of the gene is associated with combined oxidative phosphorylation deficiency 17 and susceptibility to hereditary prostate cancer 2.

(ELAC2 wt Allele, NCI Thesaurus)

Fermentation is much less efficient than oxidative phosphorylation in making ATP, creating only 2 ATP per glucose while oxidative phosphorylation creates 36 ATP per glucose in mammalian cells.

(Glycolysis Pathway, NCI Thesaurus/BIOCARTA)

Mitochondria are the sites of the reactions of oxidative phosphorylation, which result in the formation of ATP.

(Mitochondrion, NCI Thesaurus)

NADH in oxidative phosphorylation in mitochondria transports chemical energy from the Kreb's cycle to the electron transport chain, but NADPH does not play this role.

(Oxidative Reactions of the Pentose Phosphate Pathway, NCI Thesaurus/BIOCARTA)

In a series of reactions two carbons in citrate are oxidized to CO2 and the reaction pathway supplies NADH for use in the oxidative phosphorylation and other metabolic processes.

Bromebric acid appears to inhibit purine synthesis, oxidative phosphorylation and DNA synthesis.

(Bromebric Acid, NCI Thesaurus)

When ATP is needed, this acetyl-CoA can enter the Krebs cycle to drive oxidative phosphorylation.

(Acetyl Group Shuttle Pathway, NCI Thesaurus/BIOCARTA)

The coenzyme NAD+ plays an essential role in cellular redox reactions, including the redox reaction linking the citric acid cycle and oxidative phosphorylation.

(Daporinad, NCI Thesaurus)

Typically small, circular, intronless, and maternally inherited, mitochondrial DNA (mtDNA) is the multicopy deoxyribonucleic acid genome of mitochondria, intracellular organelles responsible for vital respiratory chain and oxidative phosphorylation reactions in higher eukaryotes.

(Mitochondrial DNA, NCI Thesaurus)

The precise mechanism of antitumor action has not yet been elucidated, however, certain diarylsulfonylurea compounds have been shown in preliminary studies to exert antimitotic effects through their inhibition of tubulin polymerization, and others have been shown to be effective antitumor agents in animal models by the mechanism of uncoupling mitochondrial oxidative phosphorylation.
