Q. The chemiosmotic coupling hypothesis of oxidative phosphorylation proposes that adenosine triphosphate (ATP) is formed because
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 towards adenosine diphosphate (ADP)
Explanation
As per chemiosmotic hypothesis ATP synthetase becomes active in ATP formation only where there is a proton gradient having higher concentration of $H^{+}$ or protons on the inner side as composed to outer side.
