Learning Outcomes.
After completing this exercise, you should be able to:
1. Identify and describe the function of the major types of membrane proteins.
2. Identify the mechanisms that allow a substance to cross a cell membrane including diffusion, osmosis, facilitated diffusion, or active transport.
3. Predict the net movement of molecules across a cell membrane through passive transport.
