Its energy source is glucose, which it is taking up from its environment via na/glucose symporters distributed throughout the surface of its plasma membrane. by briefly adding an inhibitor of all glucose breakdown, you are able to determine that glucose accumulates in the cell at the rate of 45 μm/hr. based on this number, how many μmoles of glucose must be entering the cell per hour? (assume that one-half of the volume of the cell is composed of organelles, and thus not available for diffusion of glucose)
