i have no idea about thsi type of question...somepeople were saying there is a similar question in lippincot, but i only read kaplan...so i have no clue.....I would chose Y, cause the Y-> Z reaction needs a lot of energy, and since X->Y doesnt need energy, Y accumulates. But this is just my guess....
