(b) The GLUT system is highly selective for glucose. It also speeds up the rate of glucose transport across the membrane by as much as 100-fold when compared to the passive diffusion of glucose across a bilayer in the absence of any transport system. While impressive, this rate of transport is much slower than purely diffusion limited rate of movement (ie. the fastest a molecule can move by diffusion). Given this fact, on the blank plot below draw the expected relationship between the rate of GLUT-mediated transport and increasing [glucose]? Use the space below the graph to explain your answer. fast Transport Rate slow low [glucose] high (c) Next, use a dashed line on the same plot above to draw the shape of the curve when the amount of GLUT transporters in the membrane is cut in half. Briefly explain your answer in the space provided below the graph.
