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. |
