<prompt> Enzymes of Calvin cycle areG-6-PDSedoheptulose-7-biphosphataseGlycerol KinasePhosphoribulose kinase  <response>: The Calvin cycle is regulated by light-dependent activation of at least 5 enzymes: RubiscoRibulose Bisphosphate Carboxylase NADP:glyceraldehyde-3-phosphate dehydrogenase Fructose-1,6-bisphosphate phosphatase Sedoheptulose-1,7-bisphosphate phosphatase Ribulose-5-phosphate kinase Of these 5 enzymes, all except rubisco are regulated by the ferredoxin-thioredoxin system.
