food particles that are polar

Post by Josh » Mon Mar 12, 2007 7:13 pm

Alright, so I'm doing Biology right now and it's suckin way. I just explained why many polar molecules and ions cannot enter cells (Thanks to Darby), because there are pore proteins in cells that reject them. But the very next question is: Many food particles are polar, so how do they get inside the cell? I'm aware that it'll be because the cell wall doesn't reject them because it needs them, but I don't know how to word it properly because I can't find that section in the study guide.

Living one day at a time;
Enjoying one moment at a time;
