What is oxidative phosphorylation? | Class 11 Biology Chapter Respiration in Plants, Respiration in Plants NCERT Solutions

Q11. What is oxidative phosphorylation?

Oxidative phosphorylation is a process in which electrons are transferred from electron donors to oxygen, which acts as electron acceptor. The oxidation-reduction reactions are involved in the formation of proton gradient. The main role in oxidative phosphorylation is played by the enzyme ATP synthase (complex V). This enzyme complex consists of F0 and F1 components. The F1headpiece is a peripheral membrane protein complex and contains the site for ATP synthesis from ADP and inorganic phosphate. F0component is a part of membrane protein complex, which acts as a channel for crossing of the protons from inner mitochondrial membrane to the mitochondrial matrix. For every two protons passing through F0–F1 complex, synthesis of one ATP molecule takes place.
