NEET Botany Calvin Cycle MCQ Question
Consider a diagram of the Calvin cycle showing three main phases: Carboxylation, Reduction, and Regeneration. Which molecule is regenerated to continue the cycle after each turn?
Ribulose-1,5-bisphosphate (RuBP)
3-phosphoglycerate (3-PGA)
Triose phosphate
Oxaloacetic acid (OAA)
Correct Answer
Detailed Explanation
The Calvin cycle requires the regeneration of the CO2 acceptor molecule Ribulose-1,5-bisphosphate (RuBP) to continue the cycle uninterrupted. This is highlighted in the NCERT context as crucial for the continuation of the cycle.
