Exercise 1
Learn about Cell Transport Mechanisms and Permeability by completing the following lab simulation.
  1. Download and open the lab instruction worksheet (PDF format) for this experiment.
  2. Watch the Cell Transport video.
  3. Complete the PhysioEx Lab Experiments:
  4. Review what you've learned by downloading and completing the review sheet (PDF or RTF format) or taking the multiple-choice quiz.
Objectives:
  • To define differential permeabilty; diffusion (simple diffusion, facilitated diffusion, and osmosis); isotonic, hypotonic, and hypertonic solutions; passive and active processes of transport; bulk-phase endocytosis; phagocytosis; and solute pump.
  • To describe the processes that account for the movement of substances across the plasma membrane and to indicate the driving force for each.
  • To determine which way substances will move passively through a differentially permeable membrane (given the appropriate information on concentration differences).
