| Term | Definition |
|---|
| fluid mosaic model | asdfhsdkhasklf |
| phospholipid | both hydrophilic & hydrophobic |
| phospholipid bilayer | forms a strong barrier for the cell |
| glycolipid | carbohydrate-attached lipid |
| hydrophilic | soluble in water |
| hydrophobic | insoluble in water |
| integral protein | embedded in the membrane (hydrophilic ends and hydrophobic middles) |
| peripheral protein | found just inside or outside the membrane (hydrophilic) |
| passive transport | passages through center of membrane proteins ; each allows one specific substance to pass through |
| active transport | movement of substances across a membrane using ATP |
| diffusion | movement of particles from an area of higher concentration to one of lower concentration |
| osmosis | movement of water from an area of higher solute concentration across a partially permeable membrane |
| facilitated diffusion | where transport proteins move ions and hydrophilic molecules through a bilayer (membrane) |
| transport (channel) proteins | move ions and hydrophilic molecules through the membrane with a passageway |
| hypertonic | solution with a higher solute concentration than another |
| hypotonic | solution with a lower solute concentration than another |
| glycoprotein | carbohydrate-attached protein |
| isotonic | having equal solute concentrations |
| carrier proteins / protein pumps | molecule binds to protein - protein changes shape (using ATP) to allow molecule in |
| endocytosis | cell takes in a substance by surrounding it with its membrane |
| pinocytosis | endocytosis: taking in fluid |
| phagocytosis | endocytosis: taking in solid |
| exocytosis | cell releases a substance |
