    During dark reaction for fixation of carbon, the three carbon atoms of each molecule of PGA are derived from.

    A)  \[\operatorname{RuBP}+C{{O}_{2}}\]

    B)  \[\operatorname{RuBP}+{{H}_{2}}O\]

    C)  only RuBP                   

    D)  \[only\text{ }C{{O}_{2}}\]

    Correct Answer: A

    Solution :

    In carboxylation, Ribulose 1, 5-biphosphate (RuBP) acts as \[C{{O}_{2}}\] acceptor. 6 moles of RuBP react with 6 moles of \[C{{O}_{2}}\] and 6 moles of water giving rise to 12 moles of 3 phosphoglyceric acid.
