Question

The fluid mosaic model of cell membrane postulates that a lipid bilayer _______________.

• A. Has some embedded protein and some proteins on the surface
• B. Coated with a layer of proteins on each surface
• C. Is coated with a layer of proteins on the outer surface only
• D. Has proteins embedded in itself and none on the surface

Answer 1

The correct option is A Has some embedded protein and some proteins on the surface

The fluid mosaic model explains various observations regarding the structure of functional cell membranes. According to this biological model, there is a lipid bilayer (two molecules thick layer consisting primarily of amphipathic phospholipids) in which protein molecules are embedded and some proteins are on surface.

So the correct answers option A.
