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 <scene name='39/392339/Cv1/4'>G3P</scene>, 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.

8) R5P is converted into <scene name='94/945512/Cv/3'>ribulose-5-phosphate</scene> (Ru5P, RuP) by phosphopentose isomerase. Xu5P is converted into RuP by phosphopentose epimerase. | |||
