Can the presence of glucose itself activate the genes that will break it down? It does in bacteria through a process known as positive transcription control.

Enzymes control metabolic pathways ... where plants make glucose molecules from different raw materials. An example of a catabolic reaction is the process of food digestion, where different ...

An example of an anabolic reaction is the synthesis of glycogen from glucose. An example of a catabolic reaction ... be absorbed by the small intestine. Metabolic pathways can be reversible ...

We have demonstrated that in human and mouse cancer cell lines, activated Akt directs a direct conversion of metabolic control to aerobic glycolysis (the Warburg effect). This conversion addicts cells ...
