[Wikipedia] October 22: Enzyme kinetics

[Faraaz Damji]

  Enzyme kinetics is the study of the rates of chemical reactions that
  are catalysed by enzymes.  Enzymes are molecules that manipulate other
  molecules — the enzymes' substrates.  These target molecules bind to an
  enzyme's active site and are transformed into products through a
  series of steps known as the enzymatic mechanism.  The study of an
  enzyme's kinetics provides insights into the catalytic mechanism of
  this enzyme, its role in metabolism, how its activity is controlled in
  the cell and how drugs and poisons can inhibit its activity.  Knowledge
  of the enzyme's structure is helpful in visualizing the kinetic data.
