| hypotonic | less solute concentration than another solution |
| amphipathic | has hydrophilic and hydrophobic region |
| Davson-Danielli model | lipid bilayer model coated on both sides with hydrophilic proteins (sandwich model) |
| fluid mosaic model | model of membrane as a mosaic of amphipathic protein molecules bobbing in fluid bilayer of phospholipids |
| integral proteins | embedded in bilayer's core |
| peripheral proteins | loosely bound to membrane surface |
| glycolipid | carbohydrates proteins covalently bonded to lipids |
| glycoprotein | carbohydrates covalently bonded to proteins |
| channel protein | transport protein that functions by having a hydrophilic channel that certain molecules use as a tunnel through the membrane |
| aquaporin | channel protein that specifically facilitates osmosis |
