6) Sedoheptulose-1,7-bisphosphatase (one of only three enzymes of the Calvin cycle that are unique to plants) cleaves sedoheptulose-1,7-bisphosphate into <scene name='94/945512/Cv/1'>sedoheptulose-7-phosphate</scene>, releasing an inorganic phosphate ion into solution | 6) Sedoheptulose-1,7-bisphosphatase (one of only three enzymes of the Calvin cycle that are unique to plants) cleaves sedoheptulose-1,7-bisphosphate into <scene name='94/945512/Cv/1'>sedoheptulose-7-phosphate</scene>, releasing an inorganic phosphate ion into solution | ||
7) Fixation of a third CO2 generates two more G3P. The ketose S7P has two carbons removed by [[transketolase]], giving <scene name='94/945512/Cv/2'>ribose-5-phosphate (R5P)</scene>, and the two carbons remaining on transketolase are transferred to one of the G3P, giving another <scene name='94/942630/Cv/4'>Xu5P</scene>. This leaves one G3P as the product of fixation of 3 CO2, with generation of three pentoses that can be converted to Ru5P. | 7) Fixation of a third CO2 generates two more G3P.
