Oxidative phosphorylation means synthesis of ATP molecules with the help of energy liberated during oxidation of reduced coenzymes produced in respiration. for this ATP synthase is used which is on head piece/F1 which is inner to outer mitochondrial membrane.so the given statement is incorrect.it should be inner mitochondrial membrane.

Incorrect Statement: Oxidative phosphorylation takes place in the outer mitochondrial membrane.
Explanation:
Introduction to Oxidative Phosphorylation:
Oxidative phosphorylation is the process by which ATP (adenosine triphosphate) is synthesized using energy derived from the electron transport chain (ETC) located in the inner mitochondrial membrane. It is the final step of cellular respiration and occurs in eukaryotic cells.
The Location of Oxidative Phosphorylation:
Oxidative phosphorylation takes place in the inner mitochondrial membrane, not the outer mitochondrial membrane. The inner mitochondrial membrane is highly folded into structures called cristae, which increases the surface area available for the ETC and ATP synthesis.
The Role of the Outer Mitochondrial Membrane:
The outer mitochondrial membrane separates the mitochondrion from the cytosol and acts as a selective barrier, controlling the passage of molecules in and out of the mitochondrion. It contains porin proteins that allow the passage of small molecules (<5000 da)="" freely.="" the="" outer="" mitochondrial="" membrane="" serves="" as="" a="" protective="" barrier="" for="" the="" inner="" mitochondrial="" membrane="" and="" other="" mitochondrial="">
The Role of the Inner Mitochondrial Membrane:
The inner mitochondrial membrane is the site of oxidative phosphorylation. It contains the complexes of the electron transport chain, including complex I (NADH dehydrogenase), complex II (succinate dehydrogenase), complex III (cytochrome bc1 complex), complex IV (cytochrome c oxidase), and ATP synthase (complex V). These complexes work together to transfer electrons from electron donors (NADH, FADH2) to electron acceptors (oxygen) and generate a proton gradient across the inner mitochondrial membrane.
Conclusion:
The statement that oxidative phosphorylation takes place in the outer mitochondrial membrane is incorrect. Oxidative phosphorylation occurs in the inner mitochondrial membrane, where the electron transport chain complexes are located. The outer mitochondrial membrane primarily acts as a protective barrier and regulates the passage of molecules in and out of the mitochondrion.
