CORRECT OPTION IS (C)

REASON:

Fluid side model of plasma membrane was proposed by singer and nicolson in 1972 according to this model the membrane does not have a uniform position of lipids and proteins but is instead mosic of the two .

Further the membrane is not solid but is Quasifluid
This nature of biomembrane is responsible for properties light repair ,dynamic nature ,ability to fuse, endocytosis etcccc fluid mosaic model postulates that the liquid molecule are present in viscous bilayered as in laminar model .

Proteins molecules occur at place both inside and on the outer side of lipid bilayer that is protein icebergs in a sea of lipids the internal proteins by the external ones are known as peripheral proteins some of the integral proteins and throughout the lipid bilayer they are called the tunal proteins or transmembrane proteins.

Glycolipids as well as glycoproteins are fall on the external fees of lipid bilayer membrane

option (c)

  • In 1972 – SJ Singer and GL Nicolson proposed the fluid mosaic model as an explanation for the data and latest evidence regarding the structure and thermodynamics of cell membranes.
  • Some proteins which are embedded in the lipid layer are called integral or intrinsic proteins and they cannot be separated from the membrane.
  • There are large globular integral proteins which project beyond the lipid layer on both the sides are believed to have channels through which water- soluble materials can pass across.
  • Superficially attached proteins are called extrinsic or peripheral proteins and can be easily removed.
