WebDec 5, 2024 · The Calvin cycle reactions (Figure 8.6. 2) can be organized into three basic stages: fixation, reduction, and regeneration. In the stroma, in addition to CO 2, two other chemicals are present to initiate the Calvin cycle: an enzyme abbreviated RuBisCO, and the molecule ribulose bisphosphate (RuBP). WebCalvin and colleagues used radioactive 14CO2 (carbon dioxide labeled with 14-carbon) to determine what are the first products of carbon fixation by a culture of algae. Within 10 minutes after injecting 14CO2, many kinds of organic molecules were radioactively labeled.
