The reactions of the Calvin cycle are closely coupled to the [[thylakoid]] electron transport chain,<ref>{{Cite journal |last1=Sainis |first1=Jayashree Krishna |last2=Dani |first2=Diksha Narhar |last3=Dey |first3=Gautam Kumar |date=2003-01-01 |title=Involvement of thylakoid membranes in supramolecular organisation of Calvin cycle enzymes inAnacystis nidulans |url=https://www.sciencedirect.com/science/article/pii/S0176161704703739 |journal=Journal of Plant Physiology |volume=160 |issue=1 |pages=23–32 |doi=10.1078/0176-1617-00849 |pmid=12685042 |bibcode=2003JPPhy.160...23S |issn=0176-1617 |quote=The results suggested that the integrity of thylakoid membranes may be essential for the organisation of sequential enzymes of the Calvin cycle in vivo and facilitate their functioning.|url-access=subscription }}</ref> as the energy required to reduce the carbon dioxide is provided by [[NADPH]] produced during the [[Light-dependent reactions|light dependent reactions]]. The process of [[photorespiration]], also known as C2 cycle, is also coupled to the Calvin cycle, as it results from an alternative reaction of the [[RuBisCO]] enzyme, and its final byproduct is another [[Glyceraldehyde 3-phosphate|glyceraldehyde-3-P]] molecule.
