Calvin cycle - Wikipedia
Systems biology studies have shown that in oxygenic phototrophic bacteria, Calvin Benson cycle enzymes are extensively regulated at post-transcriptional and post-translational levels, with multiple enzyme activities connected to cellular redox status through thioredoxin.

Others call it the Calvin-Benson cycle to include the name of another scientist involved in its discovery (Figure 1). The Calvin cycle reactions (Figure 2) can be organized into three basic stages: fixation, reduction, and regeneration.
Diagram and Explanation of the Calvin Cycle - ThoughtCo
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. It was named after the American biochemist Melvin Calvin and his colleagues, who elucidated the pathway in the 1950s.
5.3: The Calvin Cycle - Biology LibreTexts
Learn how plants use the Calvin cycle to fix carbon from CO2 and make sugars in the second stage of photosynthesis. The article explains the reactions, enzymes, and products of the cycle with diagrams and examples.
Calvin-Benson-Bassham Cycle - Chemistry LibreTexts
The light-independent Calvin-Benson cycle consist of nine reactions that take place in the chloroplast stroma. Beginning with the enzyme RuBisCO, D-ribulose-1,5-bisphosphate is converted into 3-phosphoglyceric acid. It requires magnesium ion as a cofactor.
8.5: Carbon Fixation- The Calvin Cycle - Biology LibreTexts
Early studies in photosynthetic organisms have identified the Calvin-Benson cycle, the photosynthetic pathway responsible for carbon assimilation, as a redox regulated process.
5.12C: The Calvin Cycle - Biology LibreTexts
Learn how plants use the Calvin cycle to convert carbon dioxide into carbohydrate molecules using energy from the light-dependent reactions. Explore the stages, adaptations, and evolution of the Calvin cycle in different organisms.
5.3 The Calvin Cycle - Concepts of Biology | OpenStax
The Calvin-Benson cycle (CBC) evolved over 2 billion years ago but has been subject to massive selection due to falling atmospheric carbon dioxide, rising atmospheric oxygen and changing nutrient and water availability. In addition, large groups of organisms have evolved carbon-concentrating mechanisms (CCMs) that operate upstream of the CBC.
Calvin-Benson Cycle | SpringerLink
The Calvin-Benson cycle allows the synthesis of one triose from three molecules of carbon dioxide (Fig. 1 ): 12 electrons (provided by redox coenzymes like NADH or NADPH) and 9 ATP equivalents are required for bringing CO 2 to the oxidation level of the triose glyceraldehyde 3-phosphate.
Discovery of the canonical Calvin-Benson cycle - Springer
The Calvin cycle refers to the light-independent reactions in photosynthesis that take place in three key steps. Although the Calvin Cycle is not directly dependent on light, it is indirectly dependent on light since the necessary energy carriers (ATP and NADPH) are products of light-dependent reactions.
