Competitive inhibitors are _?
Correct answer: A. Homologous to substrate
- A. Homologous to substrate
- B. Analogous to substrate
- C. Smaller than substrate
- D. Larger than substrate
Explanation
Homologous to substrate: Correct, as competitive inhibitors are structurally similar (homologous) to the substrate, meaning they share a similar shape and structure that allows them to bind to the enzyme's active site, competing with the substrate.

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.
