Gluconeogenesis in bacteria

WebThe Gluconeogenesis , Also called neoglucogenesis, is a biochemical term that describes the synthesis of glucose or glycogen from substances other than carbohydrates. The literal meaning of gluconeogenesis is GLUCO-glucose; NEO - new; GENESIS - creation. In other words it is the creation of new glucose. Figure 1: Gluconeogenesis and metabolism. WebWhile many intracellular bacterial pathogens mainly rely on glucose as a preferred carbon source for their intracellular metabo- lism, others simultaneously use multiple carbon …
