Identify the incorrect statement with respect to Calvin cycle

Options

A. The carboxylation of RuBP is catalyzed by Rubisco
B. The first stable intermediate compound formed is phosphoglycerate
C. 18 molecules of ATP are synthesized during carbon fixation
D. `NADPH + H^+` produced in the light reaction is used to reduce diphosphoglycerate

Answer

C

Explanation

In Calvin cycle 18 molecules of ATP are used in carbon fixation. The overall reaction of the Calvin cycle represented as `6RUBP + 6CO_2 + 18ATP + 12NADPH rarr 6RUBP + C_6H_(12)O_(6) + 18 ADP + 12NADP + 18Di`
