Botany - Photosynthesis in Higher Plants Question with Solution | TestHub

The reduction of${\mathrm{C}\mathrm{O}}_2$to carbohydrates needs assimilatory powers, i.e., ATP and${\mathrm{N}\mathrm{A}\mathrm{D}\mathrm{P}\mathrm{H}}_2$.

In Calvin cycle,${\mathrm{C}\mathrm{O}}_2$acceptor molecule is RuBP. The enzyme catalyzing this reaction is RuBisCO. In this cycle, for formation of one mole of hexose sugar (Glucose), 18 ATP and 12 NADPH₂are used. For assimilation of one molecule of${\mathrm{C}\mathrm{O}}_2$it needs 3 ATP and$2\mathrm{ }{\mathrm{N}\mathrm{A}\mathrm{D}\mathrm{P}\mathrm{H}}_2$molecules.
