Facilitated diffusion, therefore, allows polar and charged molecules, such as carbohydrates, amino acids, nucleosides, and ions, to cross the plasma membrane. Two classes of proteins that mediate facilitated diffusion are generally distinguished.
So, the correct option 'The channels are often composed of charged or polar R groups'.

Should I drop out of University? I am a freshman, biology major and am also in a pre-med program (so you know how tough it is for me), and I didn't realize that it's very intense and tedious. I have two labs every week, I barely get chance to study during the weekdays. I don't mind studying, I'm just not used to the overload. I am bad at time management and I became unmotivated. What do I do?? If you're in college please give me advice. **IF YOU'RE NOT IN COLLEGE DO NOT ANSWER (since it doesn't apply to you)** **I added medicine since I'm a pre-med student**
