[go to this section in the Guide]

   1.  very large polar molecules
2.  very large nonpolar molecules
3.  ions
4.  small nonpolar molecules
 

Question 2
 A method of passive transport which utilizes special proteins called carrier proteins is called
   1.  facilitated diffusion
2.  simple diffusion
3.  active transport
4.  protein channels
 

Question 3
 Active transport is different from simple diffusion and passive transport in that it
   1.  does not require an input of energy
2.  involves the expenditure of energy
3.  can be used to transport molecules across the cell membrane
4.  cannot be used to transport molecules across the cell membrane
