Let us have a detailed look at Calvin Cycle or C3 cycle along with its stages. The synthesis by organisms of organic chemical compounds, especially carbohydrates, from carbon dioxide using energy obtained from light rather than from the oxidation of chemical compoundsPhotosynthesis comprises two separate processes: the light reactions and the dark reactions. The Calvin cycle is named after Melvin C. Calvin, who won a Nobel Prize in Chemistry for finding it in 1961. 1. In plants, carbon dioxide (CO2) enters the chloroplast through the stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions where sugar is synthesized. Photosynthesis takes place in two stages: light dependent reactions and the Calvin cycle. In the stroma, in addition to CO 2, two other chemicals are present to initiate the Calvin cycle: an enzyme abbreviated RuBisCO, and the molecule ribulose bisphosphate (RuBP). Meaning of Calvin Cycle: Like the photosynthetic reactions which are driven by the light energy the reactions which joint hydrogen and CO 2 to produce carbohydrate also require energy and the main source of this energy is the assimilatory power (ATP + NADPH 2) regenerated in photolysis. It is the fixation of carbon dioxide, in which a five carbon compound is RuBP accepts the carbon dioxide.As a result a six carbon compound is produced this is unstable. Later, plants and animals can turn these three-carbon compounds into amino acids, nucleotides, and more complex sugars such as starches. Meaning of Calvin Cycle 2. Calvin cycle definition is - the cycle of enzyme-catalyzed dark reactions of photosynthesis that occurs in the chloroplasts of plants and in many bacteria and that involves the fixation of carbon dioxide and the formation of a 6-carbon sugar. Plants depend on the Calvin cycle for energy and food.Other organisms, including herbivores, also depend on it indirectly because they depend on plants for food.
