| Enzyme | Speeds up a chemical reaction without itself changing, catalyst, type of protein |
| Cell Membrane | lipid bilayer, semi-permeable ( lets some things in but not others) |
| Diffusion | passive transport, from high to low concentration, like going down a hill, does not use energy, |
| Osmosis | Diffusion of water, passive transport, high to low concentration, does not use energy |
| Facilitated Diffusion | Substances that cannot diffuse across the lipid bilayer can diffuse through the cell membrane through a protein channel, does not use energy |
| Active Transport | requires energy, low to high concentration, like going up a hill |
| Receptor | areas on the cell membrane that recognize chemical signals (enzymes, hormone) |
| Passive Transport | includes diffusion and osmosis, does not use energy |
