The primary function of the dark stage reactions, also known as the Calvin Cycle, in photosynthesis is to convert carbon dioxide (CO₂) into glucose (C₆H₁₂O₆) using the energy stored in ATP and NADPH from the light-dependent reactions. This process takes place in the stroma of the chloroplasts and does not require light directly, hence the name "dark reactions."
Through a series of enzymatic reactions, carbon fixation occurs, ultimately resulting in the production of glucose, which serves as an energy source for the plant and other organisms that consume it. Additionally, the Calvin cycle helps regenerate RuBP (ribulose bisphosphate), which is necessary for continuing the cycle.
