Cellular Transport
| Term | Definition |
|---|---|
| Carrier Protein | Protein that changes shape to move particles |
| Cell membrane | Organelle in charge of maintaining homeostasis |
| Selective Permeability | Choosing certain molecules to pass through |
| Concentration Gradient | unequal distribution of particles |
| phospholipid molecule | makes up cell membrane has polar heads and nonpolar tails |
| exocytosis | cell membrane moves around vessicle to release particles |
| Cell Wall | prevents plant cells from bursting in a hypotonic solution |
| Active Transport | uses ATP to move particles from low to high |
| Passive Transport | type of transport that does not need energy to move particles from high to low |
| Osmosis | movement of only water across the membrane from high to low |
| Simple Diffusion | movement of gasses from High to Low |
| Facilitated Diffusion | movement of particles from high to low through a channel protein |
| Endocytosis | cell membrane moving around a particle to bring it in uses ATP |
| Hypotonic Solution | Water moves in blowing up cell |
| Hypertonic Solution | Water sucked out of cell causing it to shrink |
| Isotonic Solution | Water moves in and out b/c cell in equalibrium |
| Channel Protein | Protein that looks like a tunnel |
