01/11/17 page 3Post-lab Quiz ResultsYou scored 100% by answering 4 out of 4 questions correctly.1. What variable(s) increased the rate of facilitated diffusion of glucose?2. For facilitated diffusion, increasing the concentration of glucose on one side of the membrane is the same as 3. When all of the membrane carriers are engaged, or busy, we say they are4. Na+ Cl- had no effect on glucose transport because
01/11/17 page 4Review Sheet Results1. Explain one way in which facilitated diffusion is the same as simple diffusion and one way in which it is different fromsimple diffusion.2. The larger value obtained when more glucose carriers were present corresponds to an increase in the rate of glucosetransport. Explain why the rate increased. How well did the results compare with your prediction?3. Explain your prediction for the effect Na+ Cl- might have on glucose transport. In other words, explain why you pickedthe choice that you did. How well did the results compare with your prediction?
