Question
Which of the following is the primary acceptor of carbon dioxide in Calvin Cycle?
- Glucose
- 3 PGA
- RUBP
- RUBISCO
Hint:
RUBP
The correct answer is: RUBP
In the Calvin cycle the carbon dioxide acceptor molecule is RUBP, and the enzyme catalyzing this reaction is RUBISCO. The carbon dioxide acceptor in Calvin cycle is a five carbon ketose sugar- Ribulose biphosphate (RuBP). Its chemical name is Ribulose 1,5-diphosphate.
