WebMar 2, 2024 · The pathway of glycolysis can be seen as consisting of two separate phases. The first is the chemical priming phase requiring energy in the form of ATP, and the second is considered the energy-yielding phase. In the first phase, two equivalents of ATP are used to convert glucose to fructose 1,6-bisphosphate (F1,6BP). WebThis step is catalyzed by the enzyme phosphofructokinase, which can be regulated to speed up or slow down the glycolysis pathway. Step 4.
