The EMP Pathway (Embden-Meyerhof-Parnas Pathway) is another name for glycolysis. It enables the metabolic usage of glucose to produce NADH, ATP and other biosynthetic precursors, such as pyruvate or the 3-phosphoglycerate. This pathway can take place aerobically and anaerobically with the conversion of the pyruvate to the acetyl CoA, along with the association to the TCA cycle. Learn and solve some questions for NEET on EMP Pathway or glycolysis here.
