Your answer : b. The glucose transport rate will increase. Predict Question 2: What effect do you think adding Na+ Cl- will have on the glucose transport rate? Your answer : c. There will be no change in the glucose transport rate. Stop & Think Questions: What happened to the glucose transport rate when the glucose concentration was increased from 2 m M to 8 m M ? You correctly answered: a. The glucose transport rate increased. Describe the conditions that resulted in the fastest rate of glucose transport. You correctly answered: d. 700 glucose carrier proteins and 8 m M glucose Why do you think equilibrium wasn't reached? You correctly answered: b. The membrane proteins were saturated.
