The Cycles of Photophosphorylation

's only purpose is to produce ATP. Both of these cycles products are synthesized for the use of the Calvin-Benson cycle, which produces glucose, the main energy storing molecule for cells. As the Calv ... ycles back to Photosystem I and repeats until a feedback mechanism slows the production because the Calvin-Benson cycle has enough of both ATP and NADPH to produce glucose.
