  • what are the two types of inhibitors
    non-competitive
    competitive
  • what does a competitive inhibitor do
    binds to the active site
  • is the action of a competitive inhibitor reversable
    yes
  • how do you overcome the effects of a competitive inhibitor
    increasing concentration of the substrate
  • what does a non-competitive inhibitor do
    binds to the allosteric site
    which changes the shape of active site
  • are the effects of a non-competitive inhibitor reversable
    no
  • what would a graph comparing the rate of reaction when increasing the substrate look like for both inhibitors
    competitive - rate would be slower but overall would reach the same Vmax
    non-competitive - rate would be slower and would not reach the same Vmax
  • what is an allosteric regulator
    when enzyme activity is too high a non-competitive inhibitor will bind to the allosteric sites of enzymes changing the active site reducing enzyme activity
