How does a competitive inhibitor reduce the rate of an enzyme-catalysed reaction?
Answer and explanation
Correct answer: D. It binds to the active site
- Step 1: Its shape is similar to the substrate. Step 2. It occupies the active site, so fewer enzyme-substrate complexes form; more substrate reduces the effect. Answer: It binds to the active site. Why not the others: binding away from the active site is non-competitive inhibition; peptide bonds are not broken; inhibitors do not lower activation energy.
