Membrane Structure

and Function


Cell membrane
Cell Membrane

  • Describe the properties of the cell membrane

    • Discuss how their contribute to its function

  • Describe the components of the cell membrane and their arrangements

  • Discuss the current model of cell membranes

    • Discuss each of the components and their relationship to fluidity


Membrane proteins
Membrane Proteins

  • Discuss the locations and functions of membrane proteins

  • Describe the mechanism by which membrane is acquired as secretion takes place


Selective permeability
Selective Permeability

  • Describe why selective permeability is important

    • Give several examples of materials that cross

  • Discuss how hydrophobic and hydrophilic molecules are affected by the membrane

  • Describe the importance of transport proteins


Passive transport
Passive Transport

  • Define diffusion

    • Describe its mechanism and

    • Describe its importance to the cell

  • Define osmosis
