For facilitated diffusion, increasing the concentration of glucose on one side of the membrane is the same as You correctly answered: b. making the concentration gradient steeper 3. When all of the membrane carriers are engaged, or busy, we say they are You correctly answered: a. saturated. 4. Na+ Cl- had no effect on glucose transport because You correctly answered: b. sodium is not required for glucose transport in the simulation.

01/11/17 page 4 Review Sheet Results 1. Explain one way in which facilitated diffusion is the same as simple diffusion and one way in which it is different fromsimple diffusion.Your answer: 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?

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
