2. Brainstorm: How can molecules move against their concentration gradient? Need to use energy

3. Active and Passive Transport

4. Another I Love Science Presentation @ 2006-All Rights Reserved Iteachbio@mac.com

5. What is the other name for the CMB? Fluid Mosaic Model

8. Passive Transport Does osmosis or diffusion require energy. No them move along a concentration gradient

9. Facilitated Diffusion http://pr Facilitated Diffusion- molecules move down a concentration gradient with the aid of special proteins.

10. Active Transport Requires Energy ATP Moves against the concentration gradient

11. Endocytosis Transporting material into a cell by the in folding of a membrane.

12. 2 Types of Endocytoses Phagocytoses- Solid particles are ingested into the cell Pinocytosis – liquids taken into the cell.

13. Exocytosis Moves materials out of the cell
