2. What are peripheral proteins?
- Proteins that are not embedded in the lipid bilayer, and are loosely bound to the surface of the membrane
- Proteins that penetrate the hydrophobic interior of the lipid bilayer
3. What are carrier proteins?
- Proteins that alter their shapes in order to transport molecules across the cell membrane
- Proteins that allow molecules to pass freely through them and across the cell membrane
4. What did Singer & Nicolson's theory state?
- That the cell membrane is studded with proteins, with hydrophilic areas protruding
- That the cell membrane is coated on both sides with hydrophilic proteins, like a sandwich
