Respiration In Plants Question 3

Question: 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) 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) A is false but R is true.

Show Answer

Answer: (1) Both A and R are true and R is the correct explanation of A.

Explanation-

In glycolysis, ATP is indeed used at two specific steps. The first ATP is used to convert glucose into glucose-6-phosphate, and the second ATP is used to convert fructose-6-phosphate into fructose-1,6-bisphosphate. Therefore, both the assertion and the reason are true, and the reason correctly explains the assertion.
