the phosphoketolase pathway functions in heterofermentative bacteria where carbon flux through two sugar catabolic pathways to mixed acids (lactic acid and acetic acid) increases cellular ATP production. This pathway also serves as an alternative route to produce acetyl-CoA that bypasses the CO2 lost through pyruvate decarboxylation in the Embden-Meyerhof-Parnas pathway
