Question

In the plasma membrane, the quasi-fluid nature of lipid enables the lateral movement of protein within the overall bilayer.

• A. True
• B. False

Answer 1

The correct option is A True

Quasi fluid nature of the plasma membrane:

1. A quasi-fluid behaves partly as a fluid and partly as a solid.
2. A good example of a quasi-liquid is agar jelly. It looks smooth, rubbery, and hard, but it can also spread liquids.
3. Cell membranes are quasi-fluids in that they function as solids by enclosing the contents of cells and as liquids by allowing molecules to pass through by diffusion and osmosis.

Final answer: The given statement is True.
