Term | Definition |
Active Transport | Energy-requiring process in which transport proteins bind with particles and move them through a cell membrane. |
Cellular Respiration | Chemical reactions occur that break down food molecules into simpler substances and release their stored energy. |
Diffusion | A type of passive transport in cells in which molecules move from area where there are more of them to areas where there are fewer of them. |
Endocytosis | Process by which a cell takes in a substance by surrounding it with the cell membrane. |
Enzyme | A type of protein that regulates nearly all chemical reactions in a cell. |
Equilibrum | A state in which opposing forces or influences are balanced. |
Exocytosis | Process by which vesicles released their contents outside the cell. |
Fermentation | Process by which oxygen lacking cells and some one-celled organisms released small amounts of energy from glucose molecules and produce waste such as alcohol,carbon dioxide, and lactic acid. |
Inorganic Compound | Compound,such as H2O, that is made from elements other than carbon and whose atoms usually can be arranged in only one structre. |
Metabolism | The total of all chemical reaction in an organism. |
Mixture | A combination of substances in which the individual substances do not change or combine chemically but instead retain their own individual properties;combination of them. |
Organic Compound | Compound that always contain hydrogen and carbon;carbohydrates,lipids,proteins,and nucleic acids are organic compounds found in living things. |
Osmosis | A type of passive transport that occurs when water diffuses through a cell membrane. |
Passive Transport | Movement of substances through a cell membrane without the use of cellular energy;includes diffusion,osmosis,and facilitated diffusion. |
Photosynthes | Process by which plants and many other producers use light energy to produce a simple sugar from carbon dioxide and water and give off oxygen. |
