The Calvin Cycle, also known as the Calvin-Benson Cycle, refers to the set of light independent redox reactions that takes place in the chloroplasts during photosynthesis and carbon fixation that would convert carbon dioxide into the sugar glucose. The cycle is light-independent because it takes place after the energy has been captured from sunlight. What does calvin cycle mean? The Calvin cycle fixes atmospheric carbon to ribulose 1,5-bisphosphate to form the organic 3-carbon intermediate 3-phosphoglycerate for the formation of sugars. 5/6 of the molecules are used to regenerate RuBP in ach cycle, so in 3 turns of the cycle, only 1 TP is produced to make a hexose sugar.

The Calvin Cycle includes: carbon dioxide fixation, carbon dioxide reduction, and regeneration of RuBP. It is also known as the dark reactions. Also known as Calvin-Benson cycle; carbon fixation cycle. It was named after Melvin Calvin, a US scientist who played a pioneering role in mapping the complete carbon path in photosynthesis -- but Nature has a few twists for this particular life cycle. In this cycle represented in Fig. The chemical reactions that take place in a plant overnight using the energy gained from photosynthesis during the day. Slippery Words Quiz—Changing with the Times. It is a set of chemical reactions taking place in chloroplasts during photosynthesis. Every living thing on Earth depends on the Calvin cycle. © William Collins Sons & Co. Ltd. 1979, 1986 © HarperCollins Meaning of Calvin cycle. In plants, carbon dioxide (CO 2) enters the leaves through stomata, where it diffuses over short distances through intercellular spaces until it reaches the mesophyll cells.Once in the mesophyll cells, CO 2 diffuses into the stroma of the chloroplast, the site of light-independent reactions of photosynthesis. The cycle, which can proceed in darkness, begins with the reaction of CO₂ with ribulose 1,5-bisphosphate and … The process by which [CO.sub.2] is converted into sugars like glucose is known as the Calvin cycle. Source(s): College. Meaning of calvin cycle. There are three stages to the Calvin cycle. The reactions catalysed by the enzymes whose levels have been manipulated in transgenic plants, are shown in grey. Calvin cycle: Fig. The Calvin cycle is a process that plants and algae use to turn carbon dioxide from the air into sugar, the food autotrophs need to grow. Search Result for "calvin cycle": The Collaborative International Dictionary of English v.0.48: Photosynthesis \Pho`to*syn"the*sis\, n. (Plant Physiol.) 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. Learn a new word every day. The Calvin cycle showing the intermediates from the first stable carbon compound, 3-PGA, to the cabon dioxide acceptor molecule, ribulose-1,5-bisphosphate and the exit points form the cycle into the pathways of sucrose, starch, isoprenoids and shikimic acid . The Calvin cycle can be divided into three phases: Carbon fixation, Reduction and regeneration of CO 2 acceptor. “Affect” vs. “Effect”: Use The Correct Word Every Time. % Calvin cycle, The Calvin cycle: Medical dictionary [home, info] Science (3 matching dictionaries) Calvin cycle : Agricultural Thesaurus and Glossary [ home , info ] These reactions occur in the stroma of the chloroplast, which is the fluid-filled region between the thylakoid membrane and inner membrane of the organelle. 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.. The Calvin cycle builds carbohydrates from smaller molecules and is an energy-consuming process. ATP is used as an energy source and NADPH as a reducing agent to add high-energy electrons in order to synthesise the sugar. 3 turns of the Calvin cycle produce 6 molecules of TP (2 molecules of TP are made for every CO2 molecule used. Or do you just have an interest in foreign languages? B. Fixation of Carbon Dioxide 1. In the first stage an enzyme called RuBisCo pulls carbon dioxide into an organic molecule.
