Framing Question

How do varied membrane composition and the structural features of component macromolecules in different cells contribute to membrane function?

Learning Objectives

  • Draw the structure of a lipid and explain how the structure allows a lipid bilayer to spontaneously assemble in an aqueous environment.
  • Explain the importance of membrane lipid and protein component structural asymmetries in membrane function.
  • Describe the process by which membranes grow, are turned over, or are absorbed.
  • Explain why different membranes have different lipid and protein constituents.
