WebDetailed studies carried out on glucose catabolism in adult Ascaris suum have shown that glucose is metabolised using the classical Embden-Meyerhof-Pamas pathway to form phosphoenol pyruvate (PEP) ( Chart 2 ). Further metabolism of PEP is mediated by phosphoenol pyruvate carboxykinase (PEP-CK) and pyruvate kinase (PK). WebSep 21, 2024 · In contrast, phosphoketolase pathway might be the most potential one, as it splits X5P into GAP and acetyl-CoA in one step without carbon loss . This bypass has been demonstrated in vitro by Bogorad et al., which was recently used for designing artificial methanol assimilation pathways [ 36 , 37 ].
