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:

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

Step-by-Step Solution

on Glycolysis, ATP is utilised at two specific steps in the pathway. The first step is the conversion of glucose into glucose-6-phosphate, and the second step is the conversion of fructose-6-phosphate to fructose 1, 6-bisphosphate (often referred to as diphosphate in older terminology). Therefore, both the assertion and the reason are factually correct, and the reason correctly explains the specific steps mentioned in the assertion.

Exam Context & Concepts Covered

This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Respiration in Plants. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
