Webe) Sodium fluoride, commonly used to prevent tooth decay, inhibits an enzyme in glycolysis. At what concentration is it most effective? f) Would adding MgSO 4 enhance glycolysis? MgSO 4 provides Mg ++ , a cofactor necessary to activate some enzymes in glycolysis. WebSodium fluoride inhibits glycolytic enzyme enolase, which limits ex vivo consumption of glucose in the specimen. Therefore, glucose in the gray top is stable for up to 24 hours. However, metabolism does occur at a rate of 5-7% for about 4 hours from the time of draw before complete inhibition of glycolysis.
