1. Drug BB might move into red blood cells by simple diffusion through the lipid bilayer. Suppose that you place red blood cells (never before exposed to drug BB) and place them in a bathing solution containing 10 mmoles/liter BB. Graph the concentration of drug BB inside the red blood cell and in the bathing solution vs. time, assuming BB moves through the cell's membrane by diffusion and is not metabolized. The important thing is the shape of the two lines you draw, and their relationship to each other (2 pts). 2. Redraw this same graph if the red blood cells rapidly metabolize BB. Explain your answer.
