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 glucose-6-phosphate and second ATP is used in conversion of fructose-6-phosphate into fructose-1-6-diphosphate.

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.

4. A is true but R is false.

Best answer

Answer: 2. Both A and R are true and R is the correct explanation of A.

Key idea: Two ATP molecules are invested in the preparatory phase of glycolysis.

  1. Glucose + ATP \(\rightarrow\) glucose-6-phosphate (hexokinase).
  2. Fructose-6-phosphate + ATP \(\rightarrow\) fructose-1,6-bisphosphate (phosphofructokinase).

A is true, and R names exactly the two steps, so R explains A. Option 2.
