Question

In the fluid mosaic membrane model, the phospholipid bilayer

• A. Is sandwiched between two protein layers
• B. Is covered by a single protein layer
• C. Has proteins embedded in it
• D. Lies on top of a single protein layer

Answer 1

Answer: (C)

Has proteins embedded in it

In the fluid mosaic model, the phospholipid bilayer has integrated as well as peripheral proteins embedded in it. The integrated proteins are found on the inside and span across the bilayer, while the peripheral proteins are found at the periphery of the lipid layers.

So the correct answer is 'has proteins embedded in it'.
