In Calvin cycle, RuBisCO incorporates \(\mathrm{CO}_{2}\) into ribulose, 1, 5-bisphosphate which rapidly splits into
1 2 molecules of 3-PGA
2 2 molecules of 2 -PGA
3 3 molecules of 3 -PGA
4 3 molecules of 2-PGA
Explanation:
In Calvin cycle, carboxylation is the most crucial step where \(\mathrm{CO}_{2}\) is utilised for the carboxylation of RuBP. In this case \(\mathrm{CO}_{2}\) 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.

Assertion : The carbohydrate manufactured in the leaves of higher plants are distributed to roots and storage organ through phloem. Reason : The long distance movement of organic compounds is called translocation
1 Both Assertion and Reason are true and Reason is correct explanation of Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
3 Assertion is true but Reason is false.
4 Both Assertion and Reason are false.
Explanation:
Plants synthesise carbohydrate and are transported to roots and storage organs through phloem.

The first stable product of Calvin cycle has
1 2 carbon atoms
2 3 carbon atoms
3 4 carbon atoms
4 6 carbon atoms
Explanation:
The first stable product of Calvin Cycle is a \({C_3}\) acid (three carbon containing acid). Carboxylation of RuBP results in the formation of 2 molecules of 3-PGA (Phosphoglyceric acid)
