In fluid mosaic model of the cell membrane

• A

  Lipids are arranged as a continuous sheet on the membrane surface

• B

  Lipid is sandwiched between two layers of proteins

• C

  The arrangement of lipids ensures that the nonpolar tail of saturated hydrocarbons is protected from the aqueous environment.

• D

  Proteins form the fluid part of the membrane in which the lipids are embedded either intrinsically or extrinsically.
