| Question | Answer |
|---|---|
| mixture | is a combinationof substances in which individuales substancea retai8n their own properties. |
| organic compounds | always contains carbon and hydrogen and usually as associated with living things. |
| inorganic compounds | are made up from elements other than carbon. |
| enzymes | certain proteins are called enzymes regualate nearly all chemical reactions in cells. |
| passive transport | the movement of stubstaces though the cell membrane without the input of energy. |
| diffusion | this random movement of molecules from an area where there is relativily more of them into a area were there are relativily fewer of them. |
| equilibrium | occurs when moleculs of one substance are spread evenly thoughout another substance. |
| osmosis | a type of passive transport that occurs when water diffuses though a cell membrane. |
| active transport | energy-requiring process in which transport proteins bind in with partical and move them though a cell membrane. |
| endocytosis | process by a cell takes in another substance by surrounding it with the cell membrane. |
| exocytosis | process by which vesicles release their contects outside cell. |
| metabolism | a total of all chemicalreactions in a organism. |
| photosynthesis | process by which plants and many other producers use light energy to produce a simple sugar from carbon dioxide and water give off oxygen. |
| respiration | process by which producers and consumers release stored energy from food molecules. |
| fermentation | process by which oxygen-lacking cells and some one-celled organisms release small amounts of energy from glucose molecules and produce wastes such as alcohol carbon dioxide and lactic acid. |
