a卡尔文循环(Calvin cycle),又称还原戊糖磷酸循环(Reductive pentose phosphatecycle),或光合碳还原循环(Photosynthetic carbon reductioncycle),或Calvin-Benson-Bassham 循环,是在20 世纪50 年代由Melvin Calvin、Andrew Benson 及James A. Bassham 等所提出。 卡尔文循环(Calvin cycle),又称还原戊糖磷酸循环(Reductive...
Also found in: Medical, Encyclopedia. Calvin cycle n. A series of chemical reactions that occur as part of photosynthesis, in which carbon is broken away from gaseous carbon dioxide and fixed as organic carbon in compounds that are ultimately converted into sugars. [After Melvin Calvin.] ...
The Calvin cycle isthe cycle of chemical reactions performed by plants to “fix” carbon from CO2into three-carbon sugars. The Calvin cycle is also sometimes referred to as the “light independent” reactions of photosynthesis, since it is not powered directly by photons from the Sun. ... I...

The Calvin cycle(卡尔文循环) is the point at which carbon dioxide (CO2) enters the scene. This is the process that “fixes” carbon dioxide into a solid form by combining it with a five-carbon sugar to create a six-carbon sugar. (The enzyme that carries out this reaction, called rubisco...
What is the Calvin cycle? A. The process of splitting water molecules. B. The process of generating ATP. C. The light-dependent reactions. D. The light-independent reactions. 相关知识点: 试题来源: 解析 D。解析:卡尔文循环是光合作用的暗反应,即光独立反应。A 选项是光反应中的水的光解;B ...
Calvin cycle Also found in:Dictionary,Medical,Wikipedia. [′kal·vən ‚sī·kəl] (cell and molecular biology) A metabolic process during photosynthesis that uses light indirectly to convert carbon dioxide to sugar in the stroma of chloroplasts. Also known as Calvin-Benson cycle; carbon ...

This way, we understand why the Calvin cycle is dependent on the "light reactions" and why we do not refer to the Calvin cycle as the "dark reactions." Learning Objectives To understand: * the three major steps of the biochemical reactions in the Calvin cycle * the significance of Rubisco...
six carbon atoms, it takes six turns of the Calvin cycle to make one carbohydrate molecule (one for each carbon dioxide molecule fixed). The remaining G3P molecules regenerate RuBP, which enables the system to prepare for the carbon-fixation step. ATP is also used in the regeneration of ...
