Circulation in cells ok

  1. 1. Circulation in Cells
  2. 2. Cell Membrane - Allows entry and exit of materials.
  3. 3. Outside of Cell Marker Protein Receptor Protein Carbohydrate chain Cell Membrane Channel Protein Lipid Inside of Cell
  4. 4. Cells move substances through the cell membrane by a process called transport  Two Types of Transport:  Passive Transport  Active Transport
  5. 5. What is Passive Transport?  Requires no energy from cell.  Molecules move from high concentration to low concentration.  Molecules move with the concentration gradient.
  6. 6. What’s happening?
  7. 7. How would diffusion happen in a cell?
  8. 8. Osmosis is a type of diffusion. Cell Membrane
  9. 9. HELP WANTED! I’m a Channel, I can help!
  10. 10. Explain what is happening.
  11. 11. How is Active Transport different? 1. Active transport requires energy. 2. Molecules move from low concentration to high concentration 3. Molecules move against concentration gradient.
  12. 12. Types of Transport - Passive transport - Diffusion – molecules from high to low - http://highered.mcgrawhill.com/sites/0072495855/student_view0/chapter2/animation__how_diffusion_works.html - Osmosis – water from high to low - http://highered.mcgrawhill.com/sites/0072495855/student_view0/chapter2/animation__how_osmosis_works.html - Active transport - http://highered.mcgrawhill.com/sites/0072495855/student_view0/chapter2/animation__how_facilitated_diffusion_works.html - Endocytosis – taking in - Phagocytosis – solids - http://highered.mcgrawhill.com/sites/0072495855/student_view0/chapter2/animation__phagocytosis.html - Pinocytosis - liquids - Exocytosis - Removal off
