The Calvin–Benson cycle proceeds in three phases that are highly coordinated in the chloroplast these three phases namely--Carboxylation, Reduction and Regeneration. The following statements are not related to the three phases of Calvin–Benson cycle:

#Unit 6. System Physiology – Plant

On the basis of Stoichiometry, Six molecules of ATP and six molecules of NADPH are consumed in reduction phase
1,3-bisphosphoglycerate is reduced to six molecules of glyceraldehyde3-phosphate with the concurrent release of six molecules of inorganic phosphate in reduction phase
In regeneration, which restores the CO2 acceptor ribulose 1,5-bisphosphate, at steady state, the input of CO2 equals the output of triose phosphate
In carboxylation reaction, Ribulose 1,5-bisphosphate is carboxylated into 3-Phosphoglycerate via rubisco and it uses 3 molecules of CO2 and ATP
