the chemiosmotic coupling hypothesis of oxidative phosporylaion propass that adenosine triphoshate (ATP) is formed becouse

Options

A. high energy bonds are formed in mitochondrial proteins
B. ADP is pumped out of the matrix into the intermembrane space
C. a proton gradient forms across the inner membrane
D. there is a change in the permeability of the inner mitochondrial membrane toward Adenosine Diphosphate (ADP)

Answer

C

Explanation

The production of ATP with the help of energy liberated during oxidation of reduced coenzymes and terminal oxidation is called oxidative phosphorylation . Peter Mitchell (1961) gave a hypothesis known as chemiosmotic hypothesis for ATP synthesis .According to this when electrons flow from dual proton, electron carrier to a non-hydrogen carrier the `H^(+)` are released and expelled into the intermembrane space and thus creates a proton gradient with higher concentration of `H^(+)` in the inter membranous space than matrix.
Due to the proton motive force the portons flow back and energy liberated during this back flow of protons activate ATPase present in `F_(1)` head to synthesize ATP.
