METABOLIC PATHWAYS. “Centrally located within this network are the sugar phosphate reactions of glycolysis and the pentose phosphate pathway. Together with the overlapping reactions of the Entner–Doudoroff pathway and of the Calvin cycle, they provide the precursor metabolites required for the synthesis of RNA, DNA, lipids, energy and redox coenzymes and amino acids—key molecules required for life.”
