Outline

1	Cell Transport Biology 138
2	How Cells Eat & Drink
3	Diffusion
4	Diffusion In Action http://www.emc.maricopa.edu/faculty/farabee/BIOBK/BioBooktransp.html#Cells%20and%20Diffusion When molecules of a substance are in equal concentrations on both sides of a membrane, the molecules are said to have reached dynamic equilibrium.
5	Osmosis In Blood Cells
6	Osmosis In Plant Cells
7	Types of Solutions Hypertonic Solution = higher concentration of water in the cell than outside the cell Hypotonic Solution = higher concentration of water outside the cell than inside the cell Isotonic Solution = equal concentrations of water inside and outside the cell
8	Facilitated Diffusion http://tidepool.st.usm.edu/crswr/facdifmov.html
9	Active Transport Requires energy Moves molecules against their concentration gradient (from low concentration to high concentration).
10	Endocytosis (Remember, there are two types) Phagocytosis Cell “eating” Pinocytosis Cell “drinking”
11	Phagocytosis
12	Pinocytosis The same as phagocytosis, only this is cell “drinking,” where the cell membrane engulfs liquids rather than solids.
13	Exocytosis
14	Endocytosis and Exocytosis
15	Sodium-Potassium Pump http://www.hbcollege.com/chem/biochem/GarrettGrisham/Animations/IonPump.html
