Given below are two statements : One is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): ATP is used at two steps in glycolysis .
Reason (R): First ATP is used in converting glucose into glocose-6-phosphate and second ATP is used in conversion of fructose-6-phosphate into fructose-1-6-diphoshate.
In the light of the above statements, choose the correct answer from the options given below :
1. (A) is False but (R) is True.
2. Both (A) and (R) are True and (R) is the correct explanation of (A).
3. Both (A) and (R) are True but (R) is NOT the correct explanation of (A).
