Describe Plasma membrane with reference to Fluid Mosaic model.  

1 Answer

Answer :

Ans: Fluid Mosaic model was proposed by Singer and Nicholson. This model states that plasma membrane is semi-solid. It has bimolecular fluid like lipid zone in which the solid like proteins are embedded in mosaic manner. The proteins may be either superficially present over the lipid bilayer (Peripheral proteins) or embedded either completely or partially (Intrinsic proteins). This model best explains the functions of plasma membrane. Hence it is most acceptable model.
