    Directions for: The questions consist of two statements each, printed as assertion and reason. While answering these questions you are required to choose any one of the following five responses A. If both the Assertion and the Reason are true and the Reason is a correct explanation of the Assertion. B. If both the Assertion and the Reason are true but the Reason is not a correct explanation of Assertion. C. If the Assertion is true but the Reason is false. D. If both the Assertion and the Reason are false. E. If Assertion is false but Reason is true.

    Assertion: Six molecules of \[C{{O}_{2}}\] and twelve molecules of \[NADP{{H}^{+}}+{{H}^{+}}\] and 18 ATP are used to form one hexose molecules. Reason: Light reaction results in formation of ATP and \[NADP{{H}_{2}}\].

    A) A

    B)                                       B                            

    C)       C                            

    D)        D           

    E)  E

    Correct Answer: B

    Solution :

    Six molecules of \[C{{O}_{2}}\] enter Calvin cycle to produce one hexose molecule where 18 ATP and \[12\,NADPH+{{H}^{+}}\]  molecules are used up. The light reaction of photosynthesis results in ATP and \[NADP{{H}_{2}}\] formation.
