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.
A A is false but R is true. B Both A and R are true and R is the correct explanation of A C Both A and R are true but R is NOT the correct explanation of A. D A is true but R is false.
