STANDARD Botany Calvin Cycle MCQ Question
Identify the incorrect statement with respect to Calvin cycle
The carboxylation of RuBP is catalyzed by Rubisco
The first stable intermediate compound formed is phosphoglycerate
18 molecules of ATP are synthesized during carbon fixation
NADPH + H⁺ produced in the light reaction is used to reduce diphosphoglycerate
Correct Answer
Detailed Explanation
In Calvin cycle, 18 molecules of ATP are used in carbon fixation. The overall reaction of the Calvin cycle is represented as 6RuBP + 6CO₂ + 18 ATP + 12NADPH → 6RuBP + C₆H₁₂O₆ + 18 ADP + 12NADP.
