STANDARD Botany Calvin Cycle MCQ Question
The Calvin cycle proceeds in three stages 1. Reduction, during which carbohydrate is formed at the expense of the photochemically made ATP and NADPH 2. Regeneration, during which the carbon dioxide acceptor ribulose-1, 5-biphosphate is formed 3. Carboxylation, during which carbon dioxide combines with ribulose-1, 5-biphosphate Identify the correct sequence
3-1-2
3-2
1-2-3
2-1-3
Correct Answer
Detailed Explanation
