  1. Passive Transport Ch 8

  2. Some molecules like water can pass through the plasma membrane by simple ________ diffusion Plasma membrane

  3. ENERGY If the cells uses NO_______ to move the particles, the movement across the membrane is called __________________ PASSIVE TRANSPORT passive transport ATP Plasma membrane

  4. H+ H+ H+ H+ H+ Passive transport of material across a membrane using transport proteins is called _______________ Facilitated Diffusion

  5. FACILITATED DIFFUSION USES TRANSPORT PROTEINS TO MOVE MOLECULES

  6. Some proteins are _______ proteins. This allows movement with the concentration gradient and requires NO ENERGY from the cell. Channel

  7. channel protein

  8. channel protein

  9. Some proteins are _______ proteins. They have a very specific shape and allow only one molecule (or group of closely related molecules) to pass through. Carrier

  10. Carrier Protein Step one Step two

  11. Channel Carrier Channel Carrier

  12. One molecule in one direction More than one molecule together Moves molecules simultaneously in opposite directions

  13. All of these are examples of PASSIVE TRANSPORTandrequireNO ENERGY FROM THE CELL Diffusionimplies that the molecules are all moving with (down) the concentration gradient
