NameCalvin cycle
DescriptionYES NO The Calvin cycle is the primary means of CO2 fixation in the biosphere. The characteristic enzyme, essential to this pathway and not part of other basic pathways, is ribulose bisphosphate carboxylase (rubisco), which carboxylates a five-carbon sugar to give two molecules of the 3-carbon 3-phospho-D-glycerate. Other enzymes of this cycle overlap with glycolysis/gluconeogenesis and the pentose phosphate pathway. The net result of six turns carboxylations is the creation of one six-carbon glucose-1-phosphate molecule. Note that rubisco large subunit homologs are known in some species that lack a Calvin cycle. The reverse TCA cycle is one alternative means of C02 fixation.
