Solution:
For a total of 6 molecules of fixed carbon dioxide, the final stoichiometry of the Calvin cycle can be summarized in the following equation:
This would represent the formation of a 6-carbon phosphate sugar molecule.
Now, the Calvin cycle uses chemical energy from ATP to combine six carbon atoms from six CO2 molecules with 12 hydrogens from NADPH to produce one molecule of glucose. So that, we can conclude that the correct answer is:
