Flashcards
Calvin Cycle Starting Material
Calvin Cycle Starting Material
The Calvin cycle begins when carbon dioxide (CO2) combines with a five-carbon carbohydrate called RuBP (ribulose bisphosphate).
Calvin Cycle Output (per 3 CO2)
Calvin Cycle Output (per 3 CO2)
For every three molecules of CO2 that enter the Calvin cycle, the cycle produces six molecules of 3-PGA (3-phosphoglycerate).
