NEET 2026 Botany Calvin Cycle MCQ Question
How many ATP and NADPH molecules are required to make one molecule of glucose through the Calvin pathway?
18 ATP and 12 NADPH
12 ATP and 18 NADPH
24 ATP and 18 NADPH
6 ATP and 12 NADPH
Correct Answer
Detailed Explanation
Each turn of the Calvin pathway utilizes 3 ATP and NADPH⁺H⁺ molecules for fixation of 1 CO₂ molecule. For 1 glucose, 6 turns are required, hence 18 ATP and 12 NADPH⁺H⁺ are required for glucose synthesis.
