Enzyme inhibitors

• Complete the following about competitive inhibitors.

  • A molecule that is the same/similar shape as the substrate
  • binds to the active site
  • prevents enzyme-substrate complexes from forming
• Complete the following about non-competitive inhibitors.

  • A molecule that binds to an enzyme at the allosteric site
  • causing the active site to change shape
  • preventing enzyme-substrate complexes from forming
• What happens to competitive inhibitors if you add more substrates?

  If you add more substrate this will out-compete the inhibitor, knocking them out of the active site.
• What happens to non-competitive inhibitors if you add more substrates?

  The rate of reaction doesn't change as the substrate is no longer complementary to the active site.
• What forms when a inhibitor binds to an enzyme?

  an enzyme-inhibitor complex forms
