Practice questions

1 of 37Practice questions for this set
A cell is placed in a solution where the extracellular glucose concentration is 10 mM and intracellular glucose is 2 mM. The plasma membrane is impermeable to glucose unless a specific carrier protein is present. When the carrier is expressed, glucose enters the cell rapidly; adding an ATP synthesis inhibitor does not change the rate. No vesicles form, and the carrier shows saturation at high extracellular glucose. Which mechanism best explains glucose entry under these conditions?
