A Closer Look at the Calvin Cycle. The ATP and NADPH produced by the light reactions power sugar synthesis in the Calvin cycle. In the animation of the Calvin cycle, three molecules of CO 2 are added to three molecules of ribulose bisphosphate (RuBP), a 5-carbon sugar already present in the stroma. We now have a total of eighteen carbons in the cycle (three from CO 2 and fifteen from the three molecules of RuBP).
