  1. 2. Heterogeneous mixtures with large,often visible solutes that tend to settle out
  2. 4. When large carbohydrate or protein molecules are synthesized from smaller molecules, a water molecule is removed for every bond formed
  3. 7. Have a bitter taste, feel slippery, and are proton acceptors
  4. 9. These help proteins to achieve their functional three dimensional structure
  5. 18. Reactions that contain more potential energy in their chemical bonds than did the reactants
  6. 20. Reaction whee water is mostly used to breakdown the chemical bonds that exists between a particular substance
  7. 22. These are insoluble in water
  8. 24. Covalently bonded molecules that contain carbon
  9. 25. Occurs due to the movement of charged particles
  10. 27. A group of molecules that includes sugars and starches,represent 1-2% of cell mass
  11. 29. These are negatively charged
  12. 30. These are positively charged
  13. 34. The smallest particle of a chemical substance
  14. 36. anything that occupies space and has mass
  15. 38. diverse lipids chiefly de- rived from a 20-carbon fatty acid found in all cell membranes.
  16. 40. Contain ionic bonds, lack carbon and resist decomposition
  17. 42. Another name for acids
  18. 44. The capacity to do work, or to put matter into motion
  19. 45. Atoms that have the same atomic number but different mass number.
  20. 48. Equal to the number of protons in its nucleus and is written as a subscript to the left of it’s atomic symbol
  21. 49. Substances that conduct an electrical current in solution
Down
  1. 1. Homeostasis of acid-base balance that is carefully regulated by the kidney and lungs and by chemical systems
  2. 3. Large, complex molecules containing from 100 to over 10,000 amino acids
  3. 5. Occurs when acids and bases are mixed. They react with each other in displacement reactions to form water and salt
  4. 6. The sharing of electrons
  5. 8. Bonds that are both and broken
  6. 10. Occurs whenever chemical bonds are formed, rearranged, or broken
  7. 11. The form stored in the bonds of chemical substances
  8. 12. A mixture of microscopic particles that are suspended into another medium
  9. 13. A particle made up of several atoms that are bonded together
  10. 14. Homogeneous mixtures of components that may be gases, liquids or solids
  11. 15. When atoms or molecules combine to form a large, more complex molecule
  12. 16. Chainlike molecules made of many similar or repeating units,which are joined together by dehydration synthesis
  13. 17. have a sour taste, can react with many metals, and “burn” a hole in your rug
  14. 19. Compact, spherical proteins that have at least tertiary structure
  15. 21. Energy in action
  16. 23. Reactions that release energy
  17. 26. Substances composed of two or more components physically intermixed
  18. 28. Composes 10-30% of cell mass and is the basic. structural material of the body
  19. 31. The building blocks of proteins
  20. 32. A pure substance made of the same type of molecules which are made up of several types of atoms
  21. 33. Energy that travels in waves
  22. 35. Extended and strand like proteins
  23. 37. These have no charge
  24. 39. Occurs when a molecule is broken down into smaller molecules
  25. 41. Stored energy
  26. 43. Energy directly involved in moving matter
  27. 46. An ionic compound containing cations and anions other than hydroxyl ion
  28. 47. The transferring of electrons
  29. 50. Globular proteins that act as biological catalysts
