The Calvin cycle is a series of biochemical reactions that occur in the stroma of chloroplasts in photosynthetic organisms. It is part of the process of photosynthesis.
The primary purpose of the Calvin cycle is to convert carbon dioxide (
) into glucose (
), which is a sugar molecule that can be used by the plant for energy.
The Calvin cycle involves three main stages: carbon fixation, reduction phase, and regeneration of ribulose bisphosphate (RuBP).
During the reduction phase, ATP and NADPH produced in the light-dependent reactions are used to convert 3-phosphoglycerate into glyceraldehyde-3-phosphate (G3P), which is a precursor to glucose.
The Calvin cycle does not involve the reduction of NAD+ to NADH, hydrolysis of ATP to ADP, or oxidation of glucose to produce ATP. Instead, it focuses on the conversion of carbon dioxide into glucose using ATP and NADPH.
