Given below are two statements : One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : In preparatory phase of glycolysis phosphorylation of glucose takes place and converts into glyaraldehyde-3-phosphate. Hexokinase like many other kinases requires Mg⁺⁺ for activity.
Reasons (R) : In payoff phase of glycolysis, under aerobic condition two molecules of NADH are formed in cytosol along with two molecules of pyruvate and two molecules of ATP.
In the light of the above statements, choose the most appropriate answer from the options given below :
1
Both (A) and (R) are correct and (R) is the correct explanation of (A)
2
Both (A) and (R) are correct but (R) is NOT the correct explanation of (A)
3
(A) is correct but (R) is not correct
4
(A) is not correct but (R) is correct
