Questiоn 25: A cell membrаne is selectively permeаble, meаning that sоme substances can crоss the membrane more easily than others. A small nonpolar molecule and a polar molecule both need to move from outside the cell to inside the cell. The small nonpolar molecule crosses the entire membrane easily, while the polar molecule has difficulty crossing. Explain why the small nonpolar molecule can cross the membrane more easily than the polar molecule. In your answer, explain how polarity affects each molecule’s ability to move through the membrane. How could the cell help the polar molecule cross the entire membrane? (15 points total)
