In the process of carbon fixation, three molecules of RuBP combine with three molecules of CO2 to produce three six-carbon molecules, which are then split to produce 12 molecules of 3-phosphoglycerate. After phosphorylation and reduction produce 12 glyceraldehyde 3-phosphate (G3P), what more needs to happen to complete the Calvin cycle?

what is needed to be done is reduction of the 12 glyceraldehyde 3-phosphate,  in presence of NADPH, and hydrolysis of ATP to produce 2 molecules of triose phosphate.(TP). The point of carbohydrate production in photosynthesis.

Statistically 5/6 of the TP is used to regenerate RuBP,for the cycle to continue, while the remaining 1/6 is for production of other molecules; glucose, Amino acids and lipids.

This marks the end of Calvin Cycle.

Explanation:

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.
