In Calvin cycle, RuBisCO incorporates ${CO}_{2}$ into ribulose, 1, 5-bisphosphate which rapidly splits into

A
2 molecules of 3-PGA
B
2 molecules of 2-PGA
C
3 molecules of 3-PGA
D
3 molecules of 2-PGA

Solution:

In Calvin cycle, carboxylation is the most crucial step where CO2 is utilised for the carboxylation of RuBP. In this CO2 reacts with ribulose 1,5 biphosphate to yield two molecules of 3-phosphoglycerate, a reaction catalyzed by the chloroplast enzyme ribulose biphosphate carboxylase-oxygenase, referred to as RuBisCO.
