During photosynthesis, when is CO 2 utilized?

CO2 is utilized during the Calvin cycle only, where it is fixed into organic molecules through a series of reactions. The light reactions are primarily involved in the capture of light energy and its conversion into chemical energy (ATP and NADPH), which are then used in the Calvin cycle.
