Across
  1. 3. Chain A long string of amino acids connected together by peptide bonds. A polymer for proteins.
  2. 5. what most enzymes end in
  3. 7. Element found in abundance in every living organism. Forms strong stable bonds to create organic compounds.
  4. 9. Process that changes one set of chemicals into another set of chemicals.
  5. 14. Basic building block of biological molecules.
  6. 15. Acid Basic building block (monomer) of lipids. These can be saturated or unsaturated depending on bonds.
  7. 16. enzymes that break down proteins into amino acids
  8. 18. is an example of Carbohydrates
  9. 19. example of a protein(pasta,poultry,or oil?)
  10. 20. elements or compounds produced by chemical reactions
  11. 22. elements or compounds that enter into a chemical reaction
  12. 23. A small polymer for carbohydrates. (Two sugars)
  13. 27. Acid Made up of nucleotides; function is to transmit and store genetic information. (DNA / RNA)
  14. 28. Made up of fatty acids and glycerol. Insoluble in water. Include waxes, oils, and fats. Provides long term energy storage and insulation.
  15. 29. Made up of simple sugars. Carbon, Hydrogen, and Oxygen in a 1:2:1 ratio. Provides quick energy.
  16. 30. that break down lipids into fatty acids and glycerol.
  17. 32. A substance produced in a chemical reaction.
  18. 35. The minimum amount of energy required to start a chemical reaction.
  19. 38. A substance on which an enzyme acts during a chemical reaction.
  20. 39. Monomer for carbohydrates. (One sugar)
  21. 40. The basic building block (monomer) of nucleic acids. Consist of 3 parts: sugar, phosphate, and a nitrogen base.
Down
  1. 1. the chemical processes that occur within a living organism in order to maintain life.
  2. 2. Alteration of the active site, when an enzyme binds to the appropriate substrate.
  3. 4. Examples of nucleic acids that transmit and store genetic information.
  4. 6. The temporary complex formed when the enzyme and substrate join.
  5. 8. The binding between the active site of an enzyme and a substrate molecule. The active site has a fixed structure, which exactly matches the structure of a specific substrate.
  6. 10. Acid Basic building block (monomer) for proteins. There are 20 different ones.
  7. 11. example of a lipid(blubber,bread,or meat?)
  8. 12. A larger polymer for carbohydrates. (Many sugars)
  9. 13. The six essential elements found in large quantities in all living things.
  10. 16. A large number of similar units (monomers) bonded together.
  11. 17. Site The part of the enzyme where the substrate will bind and the reaction will take place.
  12. 21. A (non-organic) chemical that increases the rate of a reaction without itself being changed by the reaction.
  13. 24. Addition of water to break 2 monomers apart.
  14. 25. Synthesis (Condensation) Removal of water to join 2 monomers together.
  15. 26. A chemical substance that is present at the start of a chemical reaction.
  16. 31. A giant molecule formed by joining smaller molecules. Biological molecules are macromolecules and include proteins, carbohydrates, lipids, and nucleic acids.
  17. 33. The most important class of proteins. Used to speed up the rates of biological reactions.
  18. 34. Made up of long chains of amino acids. Involved in many cell activities and important structural components of cells. Include enzymes and antibodies.
  19. 36. enzymes that break down starch into sugar.
  20. 37. Acts as a backbone with 2 fatty acids to create a phospholipid or with 3 fatty acid chains to create a triglyceride.
