Cell Transport
Term | Definition |
---|---|
Phospholipid | A lipid that is bound to phosphate, makes up majority of cell membrane |
Cell Membrane | Also called plasma membrane, regulates what enters/exits cell |
Fluid Mosaic Model | Way to represent cell membrane |
Passive Transport | Moves from high to low concentration, no ATP used |
Active Transport | Moves from low to high concentration, uses ATP |
Diffusion | Type of passive diffusion, moves from high to low concentration |
Osmosis | Water diffusing across a membrane |
Facilitated Diffusion | Diffusion through a gated channel/membrane spanning protein |
Hypertonic | Solution with more higher concentration |
Isotonic | Solution with same concentration |
Hypotonic | Solution with lower concentration |
Membrane Spanning Protein | Part of cell membrane, allows things to go through that wouldn't be able to pass through phospholipids |
Concentration | Amount of solutes per the amount of solvent |
Hydrophobic | Repels water |
Hydrophillic | Attracted to water |
