competitive inhibitors

• what affects how much the enzyme is inhibited?

  the relative concentrations of the inhibitor and the substrate
• what happens if there is a high conc of the inhibitor?

  the inhibitor will take up nearly all the active sites and hardly any of the substrate will get to the enzyme
• what happens if there is a higher conc of substrate?


  the substrate's chances of getting to an active site before the inhibitor increase

  • so increasing the conc of substrate will increase rate of reaction (up to a point)
