    Competive, Non competive, 
  31. What is an competive inhibitor
    Some what same shape as substrate and goes into the enzymes spot
  32. What is the noncompetive inhibitor
    Changes the shape of the substrate by going into a different spot
  33. What is allostenic regulation
    When a substate has two sites on the active and one the allostenic sites and the allostenic inhinbitor comes in and changes the shape of the substrate
  34. Tells reaction to stop
