AP Biology Ch. 8-10 Vocabulary
AP Biology Chapters 8-10 Vocabulary Chapter 8: Activation energy: the amount of energy that reactants must absorb before a chemical reaction will start Active site: the specific portion of an enzyme that attaches to the substrate by means of weak chemical bonds ATP: 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 Catalyst: a chemical agent that changes the rate of a reaction without being consumed by the reaction. Coenzyme: an organic molecule serving as a cofactor. Most vitamins function as coenzymes in important metabolic reactions
