Competitive inhibitors stop an enzyme from working by:

Correct answer: C. Blocking the active site of the enzyme

  • A. Changing the shape of the enzyme
  • B. Merging with the substrate instead
  • C. Blocking the active site of the enzyme
  • D. Combining with the product of the reaction

About Enzymes

Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
