Is Calvin Cycle Energy Consuming?

The Calvin cycle is the term used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules.

Does the Calvin cycle consume ATP?

The Calvin cycle is not totally independent of light since it relies on ATP and NADH, which are products of the light-dependent reactions. The light-independent reactions of the Calvin cycle can be organized into three basic stages: fixation, reduction, and regeneration.

What is consumed in the Calvin cycle?

The Calvin cycle uses the energy from short-lived electronically excited carriers to convert carbon dioxide and water into organic compounds that can be used by the organism (and by animals that feed on it). This set of reactions is also called carbon fixation. The key enzyme of the cycle is called RuBisCO.
