Why are lipids and proteins free to move laterally in membranes?

#Section 3: Genetics, Cellular and Molecular Biology
  1. The interior of the membrane is filled with liquid water.

  2. Lipids and proteins repulse each other in the membrane.

  3. Hydrophilic portions of the lipids are in the interior of the membrane.

  4. There are only weak hydrophobic interactions in the interior of the membrane.
