  1. Carbohydrate chains Proteins Cell membrane Protein channel Double Fat Layer Parts of the CellMembrane Outside of cell Inside of cell (cytoplasm) Go to Section:

  2. Homeostasis • Maintenance of a stable internal condition • Balance

  3. Vocab • Vesicle: • Membrane-covered compartments that forms when part of the cell membrane surrounds an object and pinches off

  4. Diffusion

  5. Definition: Movement of small particles from an area of high concentration to an area of low concentration, like oxygen Diffusion

  6. Definition: Movement of small particles from an area of high concentration to an area of low concentration, like oxygen High Diffusion Low

  7. Definition: Movement of small particles from an area of high concentration to an area of low concentration, like oxygen High Diffusion Low

  8. Definition: Movement of small particles from an area of high concentration to an area of low concentration, like oxygen High Diffusion Low Requires NO ATP (energy), moves only small particles

  9. Definition: Movement of small particles from an area of high concentration to an area of low concentration, like oxygen High Osmosis: the diffusion of water Diffusion Low Requires NO ATP (energy), moves only small particles

  10. Passive Transport

  11. Definition: the movement of medium particles from an area of high concentration to an area of low concentration through a protein channel Passive Transport

  12. Definition: the movement of small & large particles from an area of high concentration to an area of low concentration through a protein channel Passive Transport RequiresNOATP (ENERGY)

  13. Definition: the movement of medium particles from an area of high concentration to an area of low concentration through a protein channel Just like diffusion but through a protein Passive Transport RequiresNOATP (ENERGY)

  14. Definition: the movement of med. particles from an area of high concentration to an area of low concentration High Just like diffusion but through a protein Passive Transport Requires NO ATP (ENERGY) Low

  15. Definition: the movement of med. particles from an area of high concentration to an area of low concentration High Just like diffusion but through a protein Passive Transport Requires NO ATP (ENERGY) Low

  16. Active Transport

  17. Definition: the movement of medium particles from an area of low concentration to an area of high concentration through a protein channel Active Transport

  18. Definition: the movement of med. particles from an area of low concentration to an area of high concentration through protein channel Active Transport Requires ATP (ENERGY)

  19. Definition: the movement of med. particles from an area of low concentration to an area of high concentration through a protein channel Similar to Passive Transport but requires energy Active Transport Requires ATP (ENERGY)

  20. Definition: the movement of med. particles from an area of low concentration to an area of high concentration Low Similar to Passive Transport but requires energy Active Transport Requires ATP (ENERGY) High

  21. Definition: the movement of sm. & lg. particles from an area of low concentration to an area of high concentration Low Similar to Passive Transport but requires energy Active Transport Energy Requires ATP (ENERGY) High

  22. Endocytosis

  23. Review Transportation Through a Membrane • Diffusion • Osmosis • Facilitated Diffusion • Active Transport • Endocytosis • Exocytosis
