Because the job of bundle sheath chloroplasts is to carry out the Calvin cycle and make sugar, they often contain large starch grains.
Carbon fixation and G3P synthesis The Calvin cycle starts by using the enzyme Rubisco to fix CO 2 into five-carbon Ribulose bisphosphate (RuBP) molecules.
In contrast to C 4 metabolism, which physically separates the CO 2 fixation to PEP from the Calvin cycle, CAM temporally separates these two processes.
Their energy is used in the light-independent reactions of the Calvin cycle by the enzyme rubisco to produce molecules of the 3-carbon sugar glyceraldehyde 3-phosphate (G3P).
Dark reactions The Calvin cycle (Interactive diagram) The Calvin cycle incorporates carbon dioxide into sugar molecules.
It can waste up to half the carbon fixed by the Calvin cycle.
