| Question | Answer |
|---|---|
| transport protein that provides a tube-like opening in the plasma membrane through which particles can diffuse | channel protein |
| is used during active transport but not passive transport | energy |
| process in which cell takes in material by forming a vacuole around it | endocytosis |
| particle movement from an area of higher concentration to an area of lower concentration | passive transport |
| process by which a cell expels wastes from a vacuole | exocytosis |
| a form of passive transport that uses transport proteins | facilitated diffusion |
| particle movement from area of lower concentration to an area of higher concentration | active transport |
| transport protein that changes shape when a particle binds to it | carrier protein |
| the difusion of water through a cell membrane | osmosis |
| the movement of substances through the cell membrane without the use of energy | passive transport |
| used to help substances enter or exit the cell membrane | transport protein |
| when energy is required to move materials through cell membrane | active transport |
| swelling of a cell caused by water moving in | hypotonic |
| shrinking of a cell caused by water leaving | hypertonic |
| the same balance inside and outside a cell and doesnt change the shape of the cell | isotonic |
