  1. Ch. 6. 2 NotesThe Cell Membrane

  2. Fence with gates what goes in and out of the cell Phospholipids philic phobic loving fearing

  3. Phospholipid bilayer (Double layer) Fluid Mosaic Model Animation

  4. Flag flowing in the wind Cholesterol, transport proteins

  5. Ch. 6. 3 NotesDiffusion

  6. The movement of particles high low

  7. High Concentration Low Concentration Diffusion

  8. balanced Allows some things to cross the membrane, but keeps others out It’s like a window screen – it allows air movement, but keeps bugs out

  9. High Concentration Low Concentration Different particles (like salt, sugar, fart smell, perfume, etc… diffusion No Small Will it ever reach equilibrium? When do the molecules stop moving?

  10. Passive Transport Diffusion Animation

  11. passive transport High Concentration Low Concentration No Large Transport proteins bring larger particles (molecules) across the membrane Will it ever reach equilibrium? When do the molecules stop moving?

  12. Facilitated Diffusion

  13. Yes both large & small Uses transport proteins to go opposite direction – from low to high concentration Will it ever reach equilibrium? When do the molecules stop moving?

  14. The 3 types of transport

  15. Oil & water The oil and water mix together, but immediately starts to separate. The oil & water continue to separate into 2 layers.

  16. It turns into a milky, creamy color and everything is mixed. It starts to separate. The top layer has lots of bubbles and the bottom is gray. The cell membrane. The egg yolk surrounded the oil to make little cells.
