  1. Station 2Graphs to show the effects of Inhibitors on Enzyme ActionNavigate your way though all of the animations clicking on explanations each timeThen complete the worksheet

  2. Normal enzyme reaction rate Rate of reaction 1 Substrate concentration

  3. Normal enzyme reaction rate Forward Explaination

  4. Normal enzyme reaction rate 2 Rate of reaction 1 Substrate concentration

  5. Normal enzyme reaction rate Forward Every active site is saturated. The rate of the reaction is at its highest. Close Explanation

  6. Normal enzyme reaction rate 3 2 Rate of reaction 1 Substrate concentration

  7. Normal enzyme reaction rate Forward Every active site is saturated, so there is no increase in the rate of reaction. Close Example

  8. Competitive Inhibitor Revise Normal enzyme reaction rate 3 2 Rate of reaction 1 Substrate concentration

  9. Non-competitive Inhibitor Revise Competitive inhibitor reaction rate 2 Rate of reaction 1 Substrate concentration

  10. Competitive Inhibitor example:An important enzyme in respiration is succinatedehydrogenase. Its substrate is succinate, which is converted into fumarate Forward Succinate A competitive inhibitor binds to the enzyme’s active site, and slows down the process. Malonate Close Explanation Succinatedehydrogenase

  11. Competitive Inhibitor example:An important enzyme in respiration is succinatedehydrogenase. Its substrate is succinate, which is converted into fumarate Forward Succinate The substrate will soon find an active site. The effect of a competitive inhibitor is to slow down the process. Malonate Close Explanation Succinatedehydrogenase

  12. Re-Revise Non competitive inhibitor 2 Rate of reaction 1 Substrate concentration

  13. Non competitive Example: Copper Sulphate and catalase Forward The shape of the active site changes because the non-competitive inhibitor has bound to an allosteric site; so preventing an enzyme-substrate complex from forming= less products formed Hydrogen peroxide Close Explanation CuSO4 Catalase

  14. Non competitive Example: Copper Sulphate and catalase Forward The reaction rate cannot reach the same point because the non-competitive inhibitors have changed the shape of some of the active sites. Hydrogen peroxide Close Explanation CuSO4 Catalase
