Competitive inhibitors compete with?
Correct answer: B. Substrate
- A. Enzyme
- B. Substrate
- C. Product
- D. Coenzyme
Explanation
Competitive inhibitors compete with the substrate for binding to the active site of an enzyme. They have a similar chemical structure to the substrate and can bind to the active site of the enzyme, preventing the substrate from binding and the catalytic reaction from occuring.

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.
