Chapter 8 EC #1

1. energy The amount of energy that reactants must absorb before a chemical reaction will start
4. The energy that matter possesses as a result of its location or spatial arrangement
5. A chemical agent that selectively increases the rate of a reaction without being consumed by the reaction.
6. The reactant on which an enzyme works
9. The capacity to cause change, especially to do work
10. A measure of molecular disorder, or randomness.
11. An adenine-containing nucleoside triphosphate that releases free energy when its phosphate bonds are hydrolyzed
12. Thermal energy in transfer from one body of matter to another.
14. A substance that reduces the activity of an enzyme by binding to a location remote from the active site

2. Any nonprotein molecule or ion that is required for the proper functioning of an enzyme
3. A process that occurs without an overall input of energy; a process that is energetically favorable.
7. The specific region of an enzyme that binds the substrate and that forms the pocket in which catalysis occurs.
8. the change in shape of the active site of an enzyme so that it binds more snugly to the substrate.
13. A macromolecule serving as a catalyst
