  • What is on the outside surface of proteins?
    hydrophobic amino acids which interact with the tails of bilayer
  • Protein channel:
    • lined with hydrophilic amino acids and is filled with water molecules
    • allow water soluble ions to diffuse through.
  • Carrier protein:
    • change shape to allow molecules or ions to the other side
  • What are the functions of extrinsic proteins?
    act as enzymes, play a role in structure and act as receptors
  • What is a glycoprotein?
    carbohydrate and protein joined together which allows cells to attach to eachother to form tissue, act as receptors for hormones and plays role in immune system.
  • What is a glycolipid?
    carbohydrate and lipid joined together which allows cell to recognise other cells.
