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