Pacemaker enzyme of glycolytic pathway
WebMar 5, 2024 · The pathway of glycolysis begins with two inputs of energy. First, glucose gets a phosphate from ATP to make glucose-6-phosphate (G6P) and later fructose-6-phosphate (F6P) gets another phosphate from ATP to make fructose-1,6-bisphosphate (F1,6BP). WebApr 5, 2024 · Complete answer: Phosphofructokinase is regarded as the pacemaker of the EMP pathway or glycolysis because it is the most important regulatory enzyme of …
