    If X molecules of ATP are utilized to produce one molecule of glucose during photosynthesis of a C3-plant and Y molecules of ATP are formed through substrate level phosphorylation during die breakdown of one molecule of glucose in aerobic respiration, then the ratio of X and Y is

    A)  3 : 1                                      

    B)  5 : 2   

    C)   1 : 1                                     

    D)  2 : 3

    Correct Answer: A

    Solution :

                     Six molecules of ATP are utilised to produce one molecule of glucose during photosynthesis of a C3 -plant and two molecules of ATP are formed through substrate level phosphorylation during the breakdown of one molecule of glucose in aerobic respiration. Hence, the rario of X and Y is 3:1.
