1. Do Now Use you notes to help you answer the questions. There is a quiz on this NEXT CLASS!

3. Review Transport with video Quick video reviewing transport – and introducing Active Transport

4. Cell Transport Passive Transport Active Transport Diffusion Osmosis Facilitated Diffusion No Energy Movement of particles down a concentration gradient Movement of water down a concentration gradient Diffusion w/ the help of a carrier protein

5. Active Transport Requires the cell to use energy. Moves materials against the concentration gradient. 3 Types Pumps (Na + - K + Pump) Endocytosis Exocytosis

6. Na + - K + Pump Sodium is pumped (energy) out. Potassium comes through as a byproduct.

7. Endocytosis Uses energy to pinch in the plasma membrane to bring in large quantities of particles.

8. Kinds of Endocytosis Pinocytosis – Brings in fluids and small particles Phagocytosis – Takes in larger things such as bacteria

9. Exocytosis Uses energy to remove large quantities of particles by fusing a vesicle to the plasma membrane.

10. Endocytosis and Exocytosis

11. Cell Transport Passive Transport Active Transport Diffusion Osmosis Facilitated Diffusion Na + - K + Pump Exocytosis Endocytosis Needs Energy Uses energy to move Na + out of the cell against the concentration gradient. Pinches plasma membrane to bring in large amounts of stuff. Fuses vesicle to plasma membrane to rid the cell of stuff.
