  3. 8. the source of energy for use and storage at the cellular level
  4. 9. the stored energy that can be used to do work
  5. 11. the energy associated with objects in motion
  6. 17. end substances after a biological process has occurred
  7. 18. the break down of complex molecules
  8. 21. the specific region of an enzyme where a substrate binds and catalysis takes place or where chemical reaction occurs
  9. 23. Reactions that have a negative change in free energy and consequently release free energy
  10. 24. a biochemical process in metabolism where the simple molecules combine to generate complex molecules
  11. 25. a group of substances that are needed for normal cell function, growth, and development

Down
  1. 1. any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron
  2. 2. a series of connected chemical reactions that feed one another
  3. 4. a measure of randomness or disorder in a system
  4. 5. they can be added together to give an overall reaction
  5. 7. a measure of energy that is available to do work
  6. 10. The substances which participate in a chemical reaction
  7. 12. a reaction that requires energy to be absorbed in order for it to take place
  8. 13. an organic molecule that binds to the active sites of certain enzymes to assist in the catalysis of a reaction
  9. 14. model proposing that the binding of a substrate or some other molecule to an enzyme causes a change in the shape of the enzyme so as to enhance or inhibit its activity
