Cellular Energetics 2

6. The specific region of an enzyme that binds the substrate and that forms the pocket in which catalysis occurs.
7. The portion of a biological system ´ s energy that can perform work when temperature and pressure are uniform throughout the system.
9. In cellular metabolism, the use of energy released from an exergonic reaction to drive an endergonic reaction.
10. The amount of energy that reactants must absorb before a chemical reaction will start

1. The reactant on which an enzyme works.
2. A spontaneous chemical reaction in which there is a net release of free energy.
3. A non spontaneous chemical reaction in which free energy is absorbed from the surroundings.
4. A chemical agent that selectively increases the rate of reaction without being consumed by the reaction.
5. An organic molecule serving as a cofactor. Most vitamins function as coenzymes in a metabolic reaction.
8. A measure of molecular disorder, or randomness
