  1. metabolism
    the sum of all chemical reaction within a living organism
  2. catabolism
    • enzyme-regulated chemical reactions that release energy.
    • involves the breakdown of complex organic compounds into simpler ones.
    • catabolic or degradative
    • generally hydrolytic reaction (reactions which use water and which chemical bonds are broken).
    • they are exergonic (produce more energy than they consume)
    • ex: occurs when cells break down sugars into carbon dioxide and water.
  3. anabolism
    • enzyme-regulated
    • energy-requiring reactions
    • the building of complex organic molecules from simpler ones
    • called anabolic or biosynthetic reactions
    • Processes often involve dehydration synthesis reactions
    • are endergonic (consume more energy than they produce
