    Which of the following reactions of Calvin cycle are directly dependant on the availability of one or both the components of assimilatory power?
    1. Formation ofglycerldehyde-3-phosphate
    2. Formation offructose-6-phosphate
    3. Regeneration of RuBP reaction
    Identify the correct combination:

    A)  only 1 and 2 are correct

    B)  only 1 and 3 are correct

    C)  only 2 and 3 are correct

    D)  1, 2 and 3 are correct

    Correct Answer: B

    Solution :

    First reaction in Calvin cycle starts when RuBP accepts \[C{{O}_{2}}.\]Thus, RuBP is very necessary for Calvin cycle, this regenerates in the last phase of this cycle. Glyceraldehyde 3 phosphate is an intermediate component of Calvin cycle, it is also very necessary for Calvin cycle.
