Cell Respiration
Cell Respiration Vocabulary List
| Term | Definition |
|---|---|
| ADP (adenosine diphosphate) | A molecule that stores and releases energy within cells. |
| Aerobic cellular respiration | The process by which cells generate energy in the presence of oxygen. |
| Alcohol (ethanol) | A type of organic compound produced in some fermentation processes. |
| Alcohol fermentation | A process where microorganisms convert sugars into alcohol and carbon dioxide. |
| Anaerobic cellular respiration | The process of generating energy in cells without the use of oxygen. |
| ATP (adenosine triphosphate) | The primary energy currency of cells. |
| Bacteria | Microscopic single-celled organisms. |
| Carbohydrate | An organic compound, such as sugars and starches, that provides energy to cells. |
| Carbon (C) | A chemical element essential for life and found in all organic compounds. |
| Carbon dioxide (CO2) | A gas produced during cellular respiration and used in photosynthesis. |
| Cellular respiration | The process by which cells release energy from food molecules. |
| Cytosol (aka cytoplasm) | The fluid portion of the cell. |
| Energy | The ability to do work or cause a change. |
| Fermentation | A process where cells generate energy without oxygen, often producing alcohol or lactic acid. |
| Glucose | A simple sugar and a primary source of energy for cells. |
| Glycolysis | The initial step of cellular respiration, breaking down glucose into smaller molecules. |
| Krebs cycle | A series of reactions in cellular respiration that further breaks down molecules. |
| Lactic acid | A compound produced in some fermentation processes and during muscle exertion. |
| Lactic acid fermentation | A process where sugars are converted into lactic acid in the absence of oxygen. |
| Mitochondria | Organelles in eukaryotic cells where cellular respiration occurs. |
| Mitochondrion | Singular form of mitochondria. |
| Muscle cell | A cell specialized for contraction and movement. |
| NAD+ | A coenzyme involved in cellular respiration. |
| NADH | The reduced form of NAD+, carrying electrons during cellular respiration. |
| Output | The end result or product of a process. |
| Oxygen (O2) | A gas essential for aerobic cellular respiration. |
| Products | Substances formed as a result of a chemical reaction. |
| Pyruvate (pyruvic acid) | A molecule produced in glycolysis, a key player in cellular respiration. |
| Reactants | Substances present at the beginning of a chemical reaction. |
| Sugar | A general term for carbohydrates, including simple sugars and complex carbohydrates. |
| input | materials or substances used in a chemical reaction or process. |
