The fluid mosaic model describes the cell membrane as
- A
A solid crystalline lattice of cholesterol with surface glycoproteins
- B
A pure protein network with embedded carbohydrates and no lipid layer
- C
A rigid lipid sheet with proteins anchored permanently in fixed positions
- Dcheck_circle
A fluid phospholipid bilayer with proteins embedded and free to drift laterally
Explanation
Phospholipids and most proteins move laterally within the bilayer — the membrane is a 2D fluid with embedded "mosaic" of proteins.
