Calvin cycle

Definition - What does Calvin cycle mean?

The Calvin Cycle is known by other names, such as the Benson-calvin cycle. It is a set of chemical reactions taking place in chloroplasts during photosynthesis. There are three stages to the Calvin cycle. In the first stage an enzyme called RuBisCo pulls carbon dioxide into an organic molecule. In the second stage, the organic molecule is reduced, meaning an electron is added.In the third stage, RuBp, the molecule that starts the cycle is regenerated, allowing the cycle to continue from stage 1.

MaximumYield explains Calvin cycle

The main role of the Calvin Cycle is to create organic products that plants need using products produced from the ATP and NADPH photosynthetic light reactions.Among the products produced are glucose, protein made from nitrogen fixed in the soil, and lipids. The cycle also creates 3 carbon molecules which are eventually converted into Hexose (c6) sugar, and glucose. The main function of the Calvin Cycle is light independent, so it is categorized as a dark reaction, meaning it needs no light to occur, or occurs during the dark cycle of the plant. The primary function of the Calvin Cycle is carbon fixation by making simple sugars from CO2 and water
