Which of the following accounts for the fluid aspect of the fluid mosaic model of plasma membranes?
A) One of the components of the membrane is water.
B) The bilayer permits diffusion of certain lipid-soluble substances.
C) The membrane is water soluble.
D) The plasma membrane is ʺfluidʺ because of the movement of substances across the membrane.
E) The individual phospholipid molecules are not bonded to one another, so the movement of certain proteins and lipids is possible within and through the bilayer.
