The main site of fluoride inhibition in the Embden Meyerhof pathway of acid____________?
Correct answer: B. Enolase
- A. ATPase
- B. Enolase
- C. Pyruvate Kinase
- D. Fructose 6 phosphatase
Explanation
Fluoride inhibits enolase, the glycolytic enzyme that converts 2-phosphoglycerate to phosphoenolpyruvate. This is why fluoride-containing tubes help preserve blood glucose by slowing glycolysis after collection.
