Botany-Electron Transport Chain
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
Detailed Explanation
In the electron transport chain, ubiquinone (also known as coenzyme Q) acts as a mobile carrier by receiving electrons from NADH and FADH2 and transferring them to the next complex. This confirms that both the assertion and reason are accurate and related.
