The larger value obtained when more glucose carriers

2. The larger value obtained when more glucose carriers were present corresponds to an increase in the rate of glucose
transport. 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 picked
the choice that you did. How well did the results compare with your prediction?
