To synthesize one glucose molecule, the Calvin cycle uses __________molecules of CO₂, _________molecules of ATP, and ________molecules of NADPH.

Metabolism is a series of basic reactions that takes place in the body. The two phases of this process are catabolism and anabolism. A catabolic reaction is one in which the larger complexes are converted into simpler ones. Anabolic reactions are the building up of larger complexes from simpler units.

Glucose is the monosaccharide unit that is produced from carbohydrates. It is the basic sugar unit that is utilized in all the metabolic processes of the body.

The glucose is broken down via the catabolic process, such as glycolysis. It is then rebuilt in the other anabolic process, such as the calvin cycle.

The process of converting carbon dioxide into sugar is known as the calvin cycle. It is the process that takes place in plants cells, particularly bundle sheath cells and mesophyll cells.

The precursors involved in this cycle are six carbon dioxide molecules, 18 ATP, and 12 NADPH. This mechanism involves three important steps: carbon fixation, reduction, carbohydrate formation (glucose), and regeneration phase.

Hence the C4 cycle or calvin cycle uses carbon dioxide to form sugar units such as glucose.
