The first stage involves the fixation of carbon dioxide, the enzyme RuBP carboxylase catalyzes this reaction
The Calvin cycle occurs independent of light
At one point in the cycle Glycerate 3-phosphate is reduced to triose phosphate
Most of the triose phosphate is used to regenerate ribulose biphosphate. Some of the triose phosphates leave the Calvin cycle and are used to produce glucose, amino and lipids.
