| Term | Definition |
|---|
| metabolism | the organic processes (in a cell or organism) that are necessary for life, the process by which your body gets energy from food |
| catabolism | breakdown of more complex substances into simpler ones with release of energy |
| degradation | The process by which any given substance is broken down into smaller parts. [breakdown reactions] |
| releases energy | [some trapped as ATP] usually as heat, shivering produces heat |
| anabolism | linking together small molecules to make larger ones. This requires the input of energy, that is utilized from catabolic reactions. |
| synthesis reactions | when two or more atoms or molecules combine to form a larger, more complex molecule. |
| require energy | active transport, have more, but yet take more from less concentration [ATP] |
| Glycolysis | [cellular event] a metabolic process that breaks down carbohydrates and sugars through a series of reactions to either pyruvic acid or lactic acid and release energy for the body in the form of ATP |
| Krebs Cycle | [cellular event] in all plants and animals: a series of enzymatic reactions in mitochondria involving oxidative metabolism of acetyl compounds to produce high-energy phosphate compounds that are the source of cellular energy |
| Electron Transport/ oxidative phosperylation | occurs in mitochondria, provides lots of energy, uses oxygen and electrons (plus protons) to generate H2O) |
