  1. 2. a chemical species that has the highest free energy and lowest concentration of those on the pathway from a substrate to a product
  2. 4. when there is no net change in the concentration of products and reactants and delta G is zero, a system is said to be at
  3. 7. type of reaction in which the free energy is positive
  4. 9. type of enzyme that cleaves molecules by the addition of water
  5. 11. a form of energy capable of doing work under conditions of constant temperature and pressure
  6. 12. type of reaction in which the free energy is negative
  7. 15. enzyme that moves functional groups within a molecule
  8. 17. accelerates rate of reaction
  9. 19. enzyme without its cofactor
  10. 20. type of enzyme that catalyzes the joining of two molecules by forming new chemical bonds, typically with the hydrolysis of ATP
  11. 21. specific region of enzyme where substrates bind
  12. 24. type of enzyme that transfers functional groups from one molecule to another
Down
  1. 1. enzymes that catalyze oxidation-reduction reactions
  2. 3. catalytically active enzyme
  3. 5. proposes that an enzyme's active site is precisely shaped to fit a specific substrate
  4. 6. reactant in an enzymatic reaction
  5. 8. an enzyme cannot alter the laws of _______ and therefore cannot alter the equilibrium of a chemical reaction
  6. 10. tightly bound coenzymes
  7. 13. non-protein chemical compound or metallic ion that is required for an enzyme's activity as a catalyst
  8. 14. type of cofactor that is not a coenzyme
  9. 16. a spontaneous reaction takes place only if delta G is _____
  10. 18. the modification of the shape of an active site in an enzyme after the substrate has been bound
  11. 22. enzyme that adds atoms or functional groups to a double bond or removes them from double bonds
  12. 23. type of cofactor that is a small organic molecule, derived from vitamins
