  4. Carrier proteins have substances that spread through the membrane. There's a binding side on each carrier protein, it fits a specific substance. When the substance fits into place, the carrier protein changes shape. The substance is then released to the other side.

  8. Polar molecules and ions are repelled by the non polar interior of the phospholipid bilayer, so they cannot get through the cell membrane easily. They use channel and carrier proteins instead to get through.
