Homework Help: bio (plasma membrane)

Posted by lou on Saturday, February 19, 2011 at 3:14pm.

I understand that the plasma membrane is composed of a polar head and non polar tail. I read in my textbook that small non-polar molecules readily pass through and that polar and non-polar repel. so how do non-polar substance pass the the polar head? please explain.
