Calculate the mass of glucose metabolized by a 57.7kg person in climbing a mountain with an elevation gain of 1210m. Assume that the work performed in the climb is four times that required to simply lift 57.7kg by 1210m.
Express your answer to three significant figures and include the appropriate units.
