Across
- 4. The energy that matter possesses as a result of its location or spatial arrangement (structure).
- 6. A measure of disorder, or randomness.
- 8. A metabolic pathway that releases energy by breaking down complex molecules to simpler molecules.
- 9. a specific site of an enzyme that binds the substrate and that forms the pocket in which catalysis occurs.
- 10. Thermal energy in transfer from one body of matter to another.
- 12. A type of fit caused by entry of the substrate, the change in shape of the active site of an enzyme so that it binds more snugly to the substrate.
- 13. The study of energy transformations that occur in a collection of matter.
- 16. A chemical agent that selectively increases the rate of a reaction without being consumed by the reaction.
- 19. type of inhibitor that reduces the activity of an enzyme by entering the active site in place of the substrate
- 20. A metabolic pathway that consumes energy to synthesize a complex molecule from simpler molecules.
- 22. Binding of a regulatory molecule to a protein at one site that affects the function of the protein at a different site
- 23. Kinetic energy due to the random motion of atoms and molecules; energy in its most random form.
- 24. An organic molecule serving as a cofactor. Most vitamins function as coenzymes in metabolic reactions.
- 27. The reactant on which an enzyme works.
- 28. The energy associated with the relative motion of objects. Moving matter can perform work by imparting motion to other matter.
Down
- 1. A macromolecule serving as a catalyst, a chemical agent that increases the rate of a reaction without being consumed by the reaction.
- 2. A type of inhibitor that reduces activity of an enzyme by binding to a location remote from the active site, changing the enzyme’s shape so that the active site no longer effectively catalyzes the conversion of substrate to product.
- 3. The totality of an organism’s chemical reactions, consisting of catabolic and anabolic pathways, which manage the material and energy resources of the organism.
- 5. A series of chemical reactions that either builds a complex molecule (anabolic pathway) or breaks down a complex molecule to simpler molecules (catabolic pathway
- 7. Energy available in molecules for release in a chemical reaction; a form of potential energy.
- 11. A nonspontaneous chemical reaction in which free energy is absorbed from the surroundings.
- 14. A spontaneous chemical reaction in which there is a net release of free energy.
- 15. Amount of energy that reactants must absorb before a chemical reaction will start
- 17. A process that occurs without an overall input of energy; a process that is energetically favorable
- 18. Any nonprotein molecule or ion that is required for the proper functioning of an enzyme.
- 21. The portion of a biological system’s energy that can perform work when temperature and pressure are uniform throughout the system.
- 25. Coupling that uses energy when released from an exergonic reaction to drive an endergonic reaction.
- 26. An inhibition of metabolic control in which the end product of a metabolic pathway acts as an inhibitor of an enzyme within that pathway.
