organelles in memrane

• glycolipid/protein?

  • lipid: act as surface receptor and stabilise membrane structure
  • protein: cell recognition and immune response. Receptors for hormones and stabilise membrane structure.
• protein channels?

  span bilayer and control entry/removal of molecules from cell (carbs and ions)
• cholesterol?

  disturbs close packing of tails and regulated membrane fluidity, important for membrane stability
