  1. adhesive
    attracted to something other than itself
  2. cohesive
    attracted to itself. causes surface tenstion in water
  3. solvent
    liquid that does the dissolving
  4. solute
    the stuff that gets dissolved
  5. Acids
    • pH less than 7
    • release H+ in solutions
  6. Bases
    • pH greater than 7
    • releases OH in solutions
  7. Enzymes are:
    • resuable
    • organic catalyists
    • proteins
    • end in "ase"
    • task specific
  8. substrate
    items that the enzyme needs to do its job. enzymes put them together or split them apart
  9. substrates bond to:
    the active site of an enzyme
  10. anabolistic enzyme
    puts together substrates
  11. catabolistic enzyme
    breaks down enzymes
  12. covalent bonds
    • stronger than ionic bonds
    • 2 non-metals bonding
  13. ionic bonds
    • weaker than covalent bonds
    • 1 non-metal and 1 metal bonding
  14. Lewis structure
    symbol with valence electrons
  15. synthesis reaction (anabolic reaction)
    putting 2 or more molecules together to make something bigger like in the process of storing energy
  16. Decomposition reaction (catabolic reaction)
    big molecule is broken down into smaller parts like when the body uses energy to get materials
  17. exchange reactions
    combine two molecules and some of their parts are substituted/rearranged
  18. Valence electrims determine:
    bondibility
  19. columns aka families
    tell valence electron number
  20. rows aka groups
    tell energy levels
  21. rule of octet
    outer (valence) number of electrons never more than 8
  22. carbohydrates' function
    • primary source of energy
    • id marker on cells
  23. types of carbs
    • simple carbs : glucose, fructose, galactose
    • complex carbs: starches
  24. elements in carbs
    C, H, O
  25. elements in lipids
    little O, C, H
  26. lipid function
    • secondary source of energy
    • cell membrane--phospholipid
    • help to dissolve fat soluable vitamins
  27. elements in proteins
    CHONS
  28. types of proteins
    • fiberous--structural proteins (ex. keratin, elastin, callogen)
    • globular--functional proteins (ex. enzymes, hormones)
  29. elements in nucleic acids
    CHONP
  30. nucleic acids
    • made of nucleotides
    • store and use genetic info ot make proteins
    • DNA, RNA
