Explanation:
In the light-independent reactions or Calvin cycle, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. ... After the energy is transferred, the energy carrier molecules return to the light-dependent reactions to obtain more energized electrons.
There are three phases to the light-independent reactions, collectively called the Calvin cycle: carbon fixation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration. Though it is called the "dark reaction", the Calvin cycle does not actually occur in the dark or during nighttime.
