| Term | Definition |
|---|---|
| Phospholipids | Lipids with polar heads and nonpolar tails. |
| Mitochondria | A cell that requires a lot of energy might contain large numbers of what organelle. |
| Eventually becomes balanced on both sides of a membrane. | As a result of diffusion, the concentration of many types of substances.... |
| Diffustion | The movement of molecules from an area of high concentration to low concentration. |
| Osmosis | Type of passive transport where water moves across a membrane from an area of high concentration to low concentration. |
| The cell swells | What will a cell do if placed in a hypotonic solution? |
| The cell shrinks | What will a cell do if placed in a hypertonic solution? |
| Ion channels | Transport proteins that allow ions to pass through the cell membrane. |
| Active Transport | Type of transport that requires ENERGY. |
| Transport proteins | Both active transport and facilitated diffusion involve what? |
| Endocytosis | Proteins and polysaccharides that are too large to move into a cell through diffusion or active transport move in by what process? |
| Exocytosis | Molecules that are too large to be moved across a cell membrane can be removed from the cell by what process? |
