Entner Doudoroff Pathway (ED Pathway) : alternate Glycolysis Cycle

Entner Doudoroff Pathway

ED pathway or Entner Doudoroff Pathway describes an alternative series of reactions that catabolise Glucose to Pyruvate using a set of enzymes different from those used in either glycolytic of the Pentose Phosphate Pathway. The ED pathway was first reported by Mitchell Doudoroff and Nathan Entner. After their discovery this cycle was given tha name … Read more
