In all photosynthetic organisms, the Calvin’s Cycle is utilized. There are three phases of the Calvin’s Cycle. In the first phase is Carbon Fixation, the second is Reduction, and the third is Regeneration. For every three molecules of CO2 that enter the cycle, the net output is one molecule of G3P. for each G3P, the cycle uses up 9 molecules of ATP and 6 molecules of NADPH2. In the photo are a surplus of plants that use this process.
