  • Cell Membrane
    • Fluid Mosaic Model
      • The components are free to move with respect to each other and the proteins embedded in the bilayer vary in shape, size and pattern.
    • Phospholipids /lipid bilayer
    • Barrier -separates contents from outside
    • Phospholipids allow fat soluble substances through.
    • Hydrophilic/ hydrophobic tails/heads
    • Hydrophilic channels
    • Glyco-protein/ glyco-lipid
    • Cholesterol effects fluidity
    • Carrier proteins allow proteins through (selective) -facilitated diffusion
      • Used for active transport
