In the Process of Carbon Fixation, Three Molecules of RuBP

Multiple Choice

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?

A) release of two G3P to make sugars and regeneration of ATP from ADP
B) release of two G3P to make sugars and regeneration of RuBP
C) release of one G3P to make sugars and regeneration of NADPH
D) release of one G3P to make sugars and regeneration of citrate
E) release of one G3P to make sugars and regeneration of RuBP
