<prompt> Fluoride inhibitsGlucose-6-phosphataseGlucokinaseHexokinaseEnolase  <response>: Ans. d Enolase Ref Harper 28th150 Enolase is the enzyme of glycolysis pathway that converts 2-phosphoglycerate into phosphoenol pyruvate and is inhibited by Fluoride. The blood is preserved with NaF.Fluoride inhibits the Enolase, which is an enzyme of glycolysis.EnzymeInhibitorPathway 1.AconitaseFluoroacetate0Krebs cycle2.L-KG dehydrogenaseArseniteKrebs cycle3.EnolaseFluoride0Glycolysis4.Succinate dehydrogenaseMalonate oxaloacetateKrebs cycle5.Glyceradehyde 3-phosphateLactoacetate dehydrogenaseGlycolysis6.MOAIproniazid0-7.Pyruvate dehydrogenaseArsenite-8.Carbonic anhydraseSulfanilamide- ESR determination:- Westergrens method: 3.8 sodium citrate solution used as anticoagulant.- Wintrobes method: 2 mg of potassium oxalate and 3 mg of Ammonium oxalate as anticoagulant double oxalate For measurement of BT, CT, PT 3.8 sodium citate solution used as anticoagulant.
