oxidative phosphorylation

n.
The process in cell metabolism by which respiratory enzymes in the mitochondria synthesize ATP from ADP and inorganic phosphate during the oxidation of NADH by molecular oxygen.

oxidative phosphorylation

n
(Biochemistry) the process by which the energy liberated by oxidation of metabolites is used to synthesize the energy-rich molecule ATP
