The Calvin cycle describes the conversion of?

The Calvin cycle describes the conversion of carbon dioxide into glucose using energy stored in ATP and NADPH, which are produced during the light-dependent reactions of photosynthesis. This process occurs in the stroma of chloroplasts and involves three main stages: carbon fixation, reduction, and regeneration of ribulose bisphosphate (RuBP). Through a series of enzymatic reactions, the cycle ultimately transforms inorganic carbon into an organic molecule, providing the building blocks for plant growth and energy storage.
