1. Cellular Transportation

3. Diffusion TO High Concentration Low Concentration

4. Equilibrium All is equal

5. Dynamic Equilibrium Particles are constantly in motion After diffusion, they continue to move Move at the same rate because no gradient exists

6. Facilitated Diffusion Required when size becomes issue Like gates in a fence Still use concentration gradient

8. Osmosis Movement of water across selectively permeable membrane Water goes, solute stays

9. Water movement related to a cell Water constantly moves in and out of the cell. (Dynamic Equilibrium) Rate at which it comes in and goes out can differ Depends upon concentration gradient Affects the shape of the cell

11. Isotonic Solution Concentration of water and solutes is equal inside and outside cell

12. Hypotonic Solution Solute concentration LOWER outside cell than outside Water enters cell Cell expands

13. Hypertonic Solution Solute concentration HIGHER outside the cell Water leaves the cell Cell shrinks

15. Active Transport If you’re active, you USE energy Requires input of energy Use ATP for energy

16. Na + /K + ATPase pump 3 Na + for 2 K +

18. Transporting the large stuff
