Type: MCQ-conceptual-Medium-Class 11
The chemiosmotic coupling hypothesis of oxidative phosphorylation proposes that adenosine triphosphate (ATP) is formed because
A
A proton gradient forms across the inner membrane
B
There is a change in the permeability of the inner mitochondrial membrane toward adenosine diphosphate (ADP)
C
High energy bonds are formed in mitochondrial proteins
D
ADP is pumped out of the matrix into the intermembrane space
Correct Answer
Option A
Detailed Explanation
Proton gradient or proton motive force required for phosphorylation of synthesis of ATP from ADP with the use of energy of oxidation-reduction, therefore, it is called oxidative phosphorylation.
