Correct answer: C. Bind to active site

  • A. Bind to allosteric site
  • B. Cannot be overcome by increasing substrate
  • C. Bind to active site
  • D. Change Vmax but not Km

About Enzyme Inhibitors

Enzyme inhibitors reduce reaction rate by interfering with enzyme-substrate interaction or catalytic activity. Coverage includes reversible competitive, non-competitive and uncompetitive inhibition, the effects of inhibitor concentration on reaction rate, and why competitive inhibition can be reduced by increasing substrate concentration.
