Across
  1. 9. Occurs whenever chemical bonds are formed, rearranged, or broken
  2. 10. These have no charge
  3. 11. The form stored in the bonds of chemical substances
  4. 13. The smallest particle of a chemical substance
  5. 15. When atoms or molecules combine to form a large, more complex molecule
  6. 16. These help proteins to achieve their functional three dimensional structure
  7. 18. Chainlike molecules made of many similar or repeating units,which are joined together by dehydration synthesis
  8. 19. Atoms that have the same atomic number but different mass number.
  9. 20. Have a bitter taste, feel slippery, and are proton acceptors
  10. 22. Contain ionic bonds, lack carbon and resist decomposition
  11. 26. Extended and strand like proteins
  12. 29. Energy directly involved in moving matter
  13. 31. A mixture of microscopic particles that are suspended into another medium
  14. 32. A pure substance made of the same type of molecules which are made up of several types of atoms
  15. 39. Bonds that are both and broken
  16. 41. Reactions that release energy
  17. 44. Reactions that contain more potential energy in their chemical bonds than did the reactants
  18. 45. Substances that conduct an electrical current in solution
  19. 46. Reaction whee water is mostly used to breakdown the chemical bonds that exists between a particular substance
  20. 47. diverse lipids chiefly de- rived from a 20-carbon fatty acid found in all cell membranes.

Down
  1. 1. Substances composed of two or more components physically intermixed
  2. 2. Heterogeneous mixtures with large,often visible solutes that tend to settle out
  3. 3. Homogeneous mixtures of components that may be gases, liquids or solids
  4. 4. have a sour taste, can react with many metals, and “burn” a hole in your rug
  5. 5. The building blocks of proteins
  6. 6. Energy in action
  7. 7. Homeostasis of acid-base balance that is carefully regulated by the kidney and lungs and by chemical systems
  8. 8. Globular proteins that act as biological catalysts
  9. 12. Occurs due to the movement of charged particles
