Chapter 8 Crossword Puzzle
Across
- 1. A metabolic pathway that consumes energy to synthesize a complex molecule from simpler molecules
- 3. A process that occurs without an overall input of energy; a process that is energetically favorable
- 6. In cellular metabolism, the use of energy released from an exergonic reaction to drive an endergonic reaction
- 10. Energy that can be associated with the relative motion of objects
- 17. the capacity to cause change
- 18. A measure of molecular disorder or randomness
- 20. An adenine-containing nucleoside triphosphate that releases free energy when it phosphate bonds are hydrolyzed. This energy is used to drive endergonic reactions in cells
- 21. A process by which a chemical agent called a catalyst selectively increases the rate of a reaction without being consumed by the reaction
- 22. The portion of a biological system’s energy that can perform work when temperature and pressure are uniform throughout the system
- 23. A metabolic pathway that releases energy by breaking down complex molecules to simpler molecules
- 24. Kinetic energy associated with the random movement of atoms or molecules;
- 25. The amount of energy that reactants must absorb before a chemical reaction will start also called free energy of activation
- 26. The totality of an organism’s chemical reactions, consisting of catabolic and anabolic pathways, which manage the material and energy resources of the organism
- 27. The study of the energy transformations that occur in a collection of matter
Down
- 2. The reactant on which an enzyme works
- 4. Energy can be transferred and transformed, but it cannot be created or destroyed.
- 5. The specific region of an enzyme that binds the substrate and that forms the pocket in which catalysis occurs
- 7. Potential energy available for release in a chemical reaction
- 8. The overall flow and transformation of energy in an organism
- 9. A spontaneous chemical reaction in which there is a net release of free energy
- 11. A nonspontaneous chemical reaction in which free energy is absorbed from the surroundings
- 12. A temporary complex formed when an enzyme binds to its substrate molecule(s)
- 13. Every energy transfer or transformation increases the entropy of the universe
- 14. A molecule with a phosphate group covalently bound to it, making it more reactive than the unphosphorylated molecule
- 15. A series of chemical reactions that either builds a complex molecule (anabolic pathway) or breaks down a complex molecule to simpler molecules (catabolic pathway)
- 16. Energy that is not kinetic
- 19. 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
