Q. Identify the incorrect statement with respect to Calvin cycle.
A) The carboxylation of $RuBP$ is catalysed by Rubisco
B) The first stable intermediate compound formed is phosphoglycerate
C) 18 molecules of ATP molecules of ATP are synthesized during carbon fixation
D) NADPH +${\ H}^{+}$ produced in light reaction is used to reduce diphosphoglycerate
Explanation
In Calvin cycle, 18 molecules of ATP are used in carbon fixation. The overall reaction of Calvin cycle represents as $6RuBP + 6CO_{2} + 18ATP + 12NADPH \rightarrow$ $6RuBP + C_{6}H_{12}O_{6} + 18ADP + 18P + 12NADP^{+}$
