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 Your answer: d. changing the direction of diffusion Correct answer: 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 Your answer: a. glucose and sodium are cotransported. Correct answer: b. sodium is not required for glucose transport in the simulation.
02/07/18 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?
