2. is the terminal electron donor
3. is not required in the glycolytic pathway
4. acts as the final hydrogen acceptor

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R): 

Assertion (A): ATP: NADH + H+ and ATP: FADH2 ratios during the oxidative phosphorylation appear to be not 3 and 2, but 2.5 and 1.5 respectively.
Reason (R): ATP synthase produces 1 ATP/3H+.


In the light of the above statements choose the correct answer from the options given below:

1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is not the correct explanation of (A).
3. (A) is true but (R) is false.
4. Both (A) and (R) are false.
