| Question | Answer |
|---|---|
| activation energy | The amount of eneergy that reactants must absorb before a chemical reaction will start; also called free energy of activation. |
| active site | The specific portion of an enzyme that attaches to the substrate by means of weak chemical bonds. |
| allosteric regulation | The binding of a molecule to a protein that affects the function of a protein at a different site. |
| anabolic pathway | A metabolic pathway that synthesizes a complex molecule from simpler compounds. Synthesis reaction- endothermic. |
| ATP (adenosine triphosphate) | An adenine containing nucleoside triphosphate that releases free energy when its phosphate bonds are hydrolyzed. This energy is used to drive endergonic reactions in cells. |
| bioenergetics | The flow of energy through an animal, taking into account the energy used for basic function, activity, growth, reproduction, and regulation, and the energy lost to the environment as heat or waste. |
| catabolic pathway | A metabolic pathway that releases energy by breaking down complex molecules to simpler compounds. |
| catalyst | A chemical agent that changes the rate of a reaction without being consumed by the reaction. |
| chemical energy | Energy stored in the bonds of molecules; a form of potential energy. |
| coenzyme | An organic molecule serving as a cofactor. Most vitamins function as coenzymes in important metabolic reactions. |
| cofactor | Any NONPROTEIN MOLECULE or ION that is required for the porper functioning of an enzyme. Cofactors can be permanently nound to the active site or may bind loosely with the substrate during catalysis. |
| competitive inhibitor | A substance that |
