Rate limiting enzyme in glycolysis: (A) Phosphofructokinase, (B) Glucose 6 dehydrogenase, (C) Pyruvate kinase, (D) Pyruvate carboxylase
Answer is A. Fructose-6-phosphate is fuher phosphorylated to fructose1,6 bisphosphate. The enzyme is phosphofructokinase. is the rate-limiting enzyme of glycolysis. It is an allosterically regulated enzyme catalyzes the second phosphorylation step of glycolysis using a second molecule of ATP is an impoant key enzyme of this pathwayRef: DM Vasudevan, 7th edition, page no: 109
