Passive Transport1
passive transport
| Question | Answer |
|---|---|
| Passive Transport | does not require energy |
| Diffusion | molecules or ions scatter evenly througout environment |
| Concentration gradient | movement of molecules form high concentration to lower concentration |
| Simple Diffusion | Nonpolar substances diffuse directly through the lipid bilayer ex. Oxygen, & Carbon dioxide |
| Osmosis | movement of water throught selectively permeable membrane |
| Toniciy | tone or shape of cells |
| isotonic solutions | equal amounts on both sides of membrane cell shape does not change |
| Hypertonic Solution | water moves out of cell faster than moves in, cell shrinks:crenation |
| Hypotonic Solution | water move in cell faster than it move out, cell swells and may burst |
| Lysis | brustin cell |
| hemolysis | bursting red blood cell |
| Facilitated diffusion | dnt pass thru lipid bilayer: transported substance either binds to protein carriers or moves through water-filled protein channels. no energy required |
| Filtration | forces water and solutes through membrane wall by hydrostatic preassure. |
