_ is a competitive inhibitor of succinic dehydrogenase.
Correct answer: A. Malonic acid
- A. Malonic acid
- B. Malic acid
- C. Fumaric acid
- D. Acetic acid
Explanation
The competitive inhibitor of succinic dehydrogenase is malonate. Malonate closely resembles the substrate succinate and binds to the active site of the enzyme, thereby inhibiting enzyme activity. Malonate is a competitive inhibitor of succinate dehydrogenase. Succinate dehydrogenase is an enzyme that plays a crucial role in both the citric acid cycle (also known as the Krebs cycle) and the electron transport chain in cellular respiration.

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.
