NEET Botany Electron Transport Chain Assertion Reason Question

Type: Assertion Reason-assertion-Hard-Class 11

Assertion (A): Ubiquinone acts as a mobile electron carrier within the inner mitochondrial membrane during the electron transport chain. | Reason (R): Ubiquinone receives electrons from both NADH and FADH2 during the citric acid cycle.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false.

Correct Answer

Option A
