    For yielding one molecule of glucose, the Calvin cycle turns

    A)  two times          

    B)  four times

    C)  six times            

    D)  eight times

    Correct Answer: C

    Solution :

                    Conversion of \[C{{O}_{2}}\] to simple (reduced) organic compounds is called \[C{{O}_{2}}\]assimilation or \[C{{O}_{2}}\]fixation or carbon fixation or Calvin cycle. Since, one molecule of carbon is fixed in one turn of the Calvin cycle, six turns of the cycle are required to fix the glucose molecule containing 6 carbon atoms.
