Glycogen (glycolysis)

Last reviewed dd mmm yyyy. Last edited dd mmm yyyy

Glycogen can liberate glucose for entry into glycolysis. Hepatocytes are capable of this pathway but instead tend to liberate glucose to the blood when cellular reserves are low; this pathway and its regulation are considered further in the submenu on glycogenolysis.

In other cells, the following reactions occur:

  • glycogen phosphorylase cleaves glycogen of 1 glucose molecule that is phosphorylated to produce glucose-1-phosphate
  • phosphoglucomutase converts glucose-1-phosphate into glucose-6-phosphate
  • glucose-6-phosphate is able to enter the glycolytic pathway
