Molecular Movement Across Cell Membranes
Molecular Movement Across Cell Membranes Element Learning Outcomes: -Explain the key role that the lipid bilayer plays in determining trans-membrane diffusion and maintaining a concentration gradient. -Compare and contrast passive, carrier mediated of facilitated transport and active transport and explain, using examples of molecules which are transported using these mechanisms and be able to explain how these movements may be interrelated -Describe the role played by the permeability constant in determining trans-membrane diffusion and the anomalous permeability of water -Describe the structure and membrane organisation of aquaporin water channels and their contribution to the trans epithelial movement of water. -Describe the sodium pump as an example of active transport and how it maintains an intracellular steady state of sodium and potassium ions
