The most common type of glycolysis is the Embden–Meyerhof–Parnas (EMP) pathway, which was discovered by Gustav Embden, Otto Meyerhof, and Jakub Karol Parnas. Glycolysis also refers to other pathways, such as the Entner–Doudoroff pathway and various heterofermentative and homofermentative pathways. However, the discussion here will be ...
It is used in the Entner–Doudoroff pathway in prokaryotes, feeding into glycolysis. 2-dehydro-3-deoxy-phosphogluconate aldolase is one of the two enzymes distinguishing this pathway from the more commonly known Embden–Meyerhof–Parnas pathway. [1]
The Entner–Doudoroff pathway is present in many species of Archaea (caveat, see following), whose metabolisms "resemble... in [their] complexity those of Bacteria and lower Eukarya", and often include both this pathway and the Embden-Meyerhof-Parnas pathway of glycolysis, except most often as unique, modified variants.

In Pyrococcus furiosus, pyruvate, water dikinase is the enzyme that catalyzes the first step of gluconeogenesis from pyruvate in the modified Embden-Meyerhof pathway (M-EMP) and is an important ATP producing reaction in the metabolism pathway. [2] [4] The modified Embden-Meyerhof pathway is a glycolytic pathway that converts glucose into ...
Jakub Karol Parnas, also known as Yakov Oskarovich Parnas (Russian: Яков Оскарович Парнас; January 16, 1884 – January 29, 1949) was a prominent Polish–Soviet biochemist who contributed to the discovery of the Embden–Meyerhof–Parnas pathway, together with Otto Fritz Meyerhof and Gustav Embden.
Meyerhof died in Philadelphia at the age of 67. [8] In addition to receiving the Nobel Prize, he was recognized for his contributions to the study of glycolysis, by the naming of the common series of reactions for the pathway in Eukaryotes as the Embden–Meyerhof–Parnas Pathway. [9]
The glycosome is a host of the main glycolytic enzymes in the pathway for glycolysis. This pathway is used to break down fatty acids for their carbon and energy. The entire process of glycolysis does not take place in the glycosome however. Rather, only the Embden-Meyerhof segment where the glucose enters into the glycosome.
The sulfoglycolytic Embden-Meyerhof-Parnas (sulfo-EMP) pathway, first identified in Escherichia coli, involves the degradation of sulfoquinovose to 2,3-dihydroxypropanesulfonate (DHPS), [3] and shares similarity with the Embden-Meyerhof-Parnas glycolysis pathway. This pathway leads to the production of the C3 intermediate dihydroxyacetone ...
