Fluid Mosaic Model of Biological Membrane
The fluid mosaic model describes the biological membrane as:
- Porous protein lattice
- Rigid protein matrix
- Phospholipid bilayer, proteins — Correct Answer
- Single lipid layer
Correct Answer: A bilayer of phospholipids with embedded proteins, fluid and flexible
The Fluid Mosaic Model describes the biological membrane as a bilayer of thick lipids with hydrocarbon chains oriented inward (forming a continuous hydrophobic phase) and hydrophilic heads oriented outward. Individual lipid molecules can move laterally, making the membrane fluid, flexible, electrically resistant and relatively impermeable to highly polar molecules.
Key Features
- Membrane proteins serve as receptors and provide selective targets for drug action.
- Proteins can freely float through the membrane.
- Intrinsic proteins extending through the full membrane thickness surround fine aqueous pores.
- Biological membranes behave as lipoids punctured by aqueous pores.
