What is oxidative phosphorylation given in chapter 14 biology class 11 ncert solutions?
Oxidative phosphorylation is the synthesis of energy-rich ATP  molecules with the help of energy liberated during oxidation of reduced coenzymes ( NADH and FADH2 ) produced in respiration. TH enzyme required for the synthesis is called ATP synthase. It is the fifth complex of ETS. During this process, a number of oxidation-reduction reactions occur and lead to the generation of a proton gradient.
