    Four things that can speed up chemical reactions are:
    1. heat
    2. increasing the concentration of reactants

  4. catalyze
    spark or trigger a rapid change
    Simple cells may have as many as 2000 different enzymes, each one catalyzing a different reaction.
  5. hydrogen peroxide
    a viscous liquid with strong oxidizing properties
    Write the chemical reaction for the breakdown of hydrogen peroxide by the enzyme catalase.
  6. substrate
    the material that is acted upon by an enzyme
    An enzyme’s efficiency increases with greater substrate concentration, but only to a point.
  7. synthesize
    combine and form a complex whole
    Enzymes are important in regulating chemical patheways, synthesizing material needed by cells, releasing energy, and transferring information.
  8. reaction
    an idea evoked by some experience
    Chemical reactions make life possible.
  9. protein
    an organic compound essential to living cells
    With few exceptions, enzymes are proteins.
  10. digestion
