He refuses to tell you anything regarding this drug, except to give you a peek at their data regarding the kinetics of uptake of this drug in kidney cells. He thinks his data support the idea that the protein is required for the uptake of his drug; his supervisor thinks his data show which this drug simply diffuses in the cell. From what you’ve learned in cell biology, which is right: your friend or his supervisor? Discuss your answer
