The wider orrcurence of glycolysis in nearly all organisms, both aerboic and anaerobic, indicates that it is one of the most ancient metabolic pathways. However, glycolysis occurs with variations in nature. The most common reaction sequence is referred to Embden-Meyerhof (a.k.a Embden-Meyerhof-Parnas; EMP) pathway converts glucose to pyruvate in all domains of life. On the other hand. a variation of the EMP pathway, know as Enter-Doudoroff (ED) pathway, occurs only in prokaryotes and describes an alternative series of reactions that catabolize glucose to pyruvate using a set of enzymes different from those used in glycolysis.
a) What are the distinct reaction of the Enter-Doudoroff pathway in comparison to Embden-Meyerhof-Parnas pathway?
b)What are ATP and NAD(P)H yields of the Entner-Doudoroff pathway im comparison to EMbden-Meyerhof-Parnas pathway?
