WebIn the Embden–Meyerhof pathway, there are two main stages. The first one is the conversion of the sugar to a common intermediate, which is glucose-6-phosphate followed by the second stage including the conversion of the intermediate into pyruvate. The class of the end product of this pathway depends upon the microorganism used. Embden Meyerhof Pathway and Entner Doudoroff Pathway are two pathways which act as the initial step of energy production.
