One is carbon fixation where the carbon molecules are broken down to create a 3-PGA. The Calvin cycle, Calvin–Benson–Bassham (CBB) cycle, reductive pentose phosphate cycle (RPP cycle) or C3 cycle is a series of biochemical redox reactions that take place in the stroma of chloroplast in photosynthetic organisms. Overall, this cycle is an anabolic pathway, which forms glucose from carbon dioxide and water. How the products of the light reactions, ATP and NADPH, are used to fix carbon into sugars in the second stage of photosynthesis.

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. The Calvin cycle reactions (Figure 5.15) can be organized into three basic stages: fixation, reduction, and regeneration. Photosynthetic organisms use sunlight to create energy which is stored in the form of several chemical compounds. This is where food chains come into play, with apex predators and carnivores at the top, supported by herbivores, who get their energy from organic plant matter. This carbon dioxide then combines with the molecule ribulose known as ribulose 1,5-bisphosphate. The Calvin cycle is a series of biochemical redox reactions that take place in the stroma of chloroplasts in photosynthetic organisms. Energy from ATP and from the reduced coenyzme NADPH is used to remove a phosphate group from 3PGA and reduce the resulting diphosphoglycerate (DPGA) to produce the 3-carbon sugar glyceraladehyde-3-phosphate (G3P).
