What is the main goal of the Calvin-Benson Cycle?

The main goal of the Calvin-Benson Cycle is to construct sugars from carbon dioxide using ATP and NADPH. This cycle, which takes place in the stroma of chloroplasts, is essential for synthesizing organic compounds that plants need for growth and energy storage. It does this by fixing carbon dioxide from the atmosphere and allowing it to be reduced to form glucose through a series of enzymatic reactions. ATP provides the energy, while NADPH provides the reducing power necessary for the conversion of carbon compounds.

This process does not involve the direct utilization of light energy, as that occurs in the light-dependent reactions of photosynthesis. Similarly, while water molecules are involved earlier in the photosynthetic process, they are not oxidized within the Calvin-Benson Cycle itself, and the transfer of electrons to chlorophyll is also a part of the light-dependent reactions rather than the Calvin Cycle.
