2019年10月4日 · The Calvin Cycle is the cycle of chemical reactions performed by plants to “fix” carbon from CO2 into three-carbon sugars. Later, plants and animals can turn these three-carbon compounds into amino acids, nucleotides, and more complex sugars such as starches.

卡尔文循环（Calvin cycle），一译开尔文循环，又称光合碳循环（碳反应）。 是一种类似于克雷布斯循环（Krebs cycle，或称柠檬酸循环）的新陈代谢过程，可使其动物质以分子的形态进入和离开此循环后发生再生。

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.

2023年2月2日 · The Calvin cycle occurs in the chloroplast stroma, the region between the thylakoid membrane and the organelle’s inner membrane just after completing the light reaction of photosynthesis. The light reaction helps the Calvin cycle by providing ATP which is its energy source, and NADPH for reducing ability.

The conversion of CO2 to carbohydrate is called Calvin Cycle or C3 cycle and is named after Melvin Calvin who discovered it. The plants that undergo the Calvin cycle for carbon fixation are known as C3 plants. Calvin Cycle requires the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase commonly called RuBisCO.

2024年11月1日 · The Calvin Cycle, also known as the C3 cycle or the dark reactions of photosynthesis, is a critical biochemical pathway through which plants convert carbon dioxide into organic compounds. Here are key facts about the Calvin Cycle that highlight its function, discovery, and importance.

2023年8月13日 · The Calvin cycle, also known as the Calvin Benson cycle or the dark reactions, is a series of biochemical reactions that take place in the stroma (fluid-filled space) of chloroplasts during photosynthesis.

Using the energy carriers formed in the first stage of photosynthesis, the Calvin cycle reactions fix CO 2 from the environment to build carbohydrate molecules. An enzyme, RuBisCO, catalyzes the fixation reaction, by combining CO 2 with RuBP.

The Calvin cycle reactions (Figure 5.15) can be organized into three basic stages: fixation, reduction, and regeneration. 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).

The Calvin cycle reactions can be organized into three basic stages: fixation, reduction, and regeneration. In the stroma, in addition to CO 2, two other molecules are present to initiate the Calvin cycle: an enzyme abbreviated RuBisCO, and the molecule ribulose bisphosphate (RuBP). RuBP has five atoms of carbon and a phosphate group on each end.
