  8. 19. Chainlike molecules made of many similar or repeating units,which are joined together by dehydration synthesis
  9. 22. These are negatively charged
  10. 26. A group of molecules that includes sugars and starches,represent 1-2% of cell mass
  11. 30. Occurs whenever chemical bonds are formed, rearranged, or broken
  12. 31. The building blocks of proteins
  13. 32. These help proteins to achieve their functional three dimensional structure
