In the process of carbon fixation,RuBP attaches a CO₂ to produce a six-carbon molecule,which is then split to produce two molecules of 3-phosphoglycerate.After phosphorylation and reduction produces glyceraldehyde 3-phosphate (G3P),what more needs to happen to complete the Calvin cycle?
A)addition of a pair of electrons from NADPH
B)inactivation of RuBP carboxylase enzyme
C)regeneration of ATP from ADP
D)regeneration of RuBP
E)regeneration of NADP⁺
