BIO: Cells
| Term | Definition |
|---|---|
| Enzyme | Special biological proteins that speed up chemical reactions in living organisms |
| Hypertonic | When there are less solutes inside the cell than outside, water moves out, and the cell gets smaller |
| Osmosis | Movement of water across a plasma membrane |
| Photosynthesis | Process plants use to make food using sunlight |
| Mitosis | Cell division in eukaryotes that makes two identical cells |
| Endocytosis | When the cell takes in large materials by surrounding and pulling them inside, uses energy |
| Selective permeability | Allows only some things to pass through |
| ADP | A molecule with less energy that can turn back into ATP when a phosphate is added |
| Homeostasis | Keeping a stable internal environment |
| Macromolecules | Large molecules made from smaller ones |
| Catalyst | A substance that speeds up a chemical reaction |
| Diffusion | Movement of particles from an area of high concentration to an area of low concentration |
| Cellular respiration | The process cells use to break down food and make energy |
| Exocytosis | When the cell pushes large materials out by releasing them through the membrane, uses energy |
| Passive transport | Movement of materials across the cell membrane without using energy |
| Hypotonic | When there are more solutes inside the cell than outside, water moves in, and the cell gets bigger |
| Isotonic | When there are equal solutes inside and outside the cell, water moves in and out at equal rates, and the cell stays the same size |
| Binary fission | Cell division in prokaryotes that makes two identical cells |
| Active transport | The movement of materials across the cell membrane that uses energy to go from low concentration to high concentration |
| Facilitated diffusion | Movement of molecules in or out of the cell with help from transport proteins |
