Question

Choose the correct answer from the alternatives given.
The following theory best explains the structure of the plasma membrane

• A. Sandwich theory
• B. Fluid-mosaic theory
• C. Unit membrane theory
• D. Electrochemical theory

Answer 1

The correct option is B Fluid-mosaic theory

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 'Fluid-mosaic theory'.
