    hydrolysis
  20. Oxidation occurs when
    a molecule loses two hydrogens and/or gains an oxygen
  21. Reduction occurs when
    a molecule gains two hydrogens and/or loses an oxygen.
  22. Image Upload
    oxidation
  23. Image Upload
    reduction
  24. Image Upload
    not reduction but addition (add 2H and 1O)
  25. anabolic and catabolic pathways
    anabolic - large complex molecules are synthesized from smaller molecules, energy from catabolic pathway

    catabolic- large complex molecules are degraded into simpler products.  A portion of the energy produced drive anabolic reactions.
