<Li> Then fixation of another CO generates two more G3P . </Li> <Li> F6P has two carbons removed by transketolase, giving erythrose - 4 - phosphate . The two carbons on transketolase are added to a G3P, giving the ketose xylulose - 5 - phosphate (Xu5P). </Li> <Li> E4P and a DHAP (formed from one of the G3P from the second CO fixation) are converted into sedoheptulose - 1, 7 - bisphosphate (7C) by aldolase enzyme . </Li> <Li> Sedoheptulose - 1, 7 - bisphosphatase (one of only three enzymes of the Calvin cycle that are unique to plants) cleaves sedoheptulose - 1, 7 - bisphosphate into sedoheptulose - 7 - phosphate, releasing an inorganic phosphate ion into solution . </Li>

Where do the light-independent reactions take place in plants who perform only c3 photosynthesis
