Irreversible steps of Glycolysis are catalysed by:: (A) Hexokinase, Phosphofructokinase, Pyruvate Kinase, (B) Glucokinase, Pyruvate Kinase, Glyceraldehyde 3 Phosphate Dehydrogenase, (C) Hexokinase, Phospho Glycerate Kinase, Pyruvate Kinase, (D) Pyruvate Kinase, Fructose 1,6 Bisphosphatase, Phospho FructoKinase
Answer is A. Ans. A. Hexokinase, Phosphofructokinase, Pyruvate Kinase(Ref: Harper 29/e page 171-174, Harper 31/e page 160,161)Remember: All the Kinases are irreversible except 1,3 Bisphospho Glycerate Kinase which is reversible.
