Glycogenesis
Glycogenesis is the formation of glycogen from glucose. Glycogen is synthesized
depending on the demand for glucose and ATP (energy). If both are present in
relatively high amounts, then the excess of insulin promotes the glucose
conversion into glycogen for storage in liver and muscle cells.
In the synthesis of glycogen, one ATP is required per glucose incorporated into
the polymeric branched structure of glycogen. actually, glucose-6-phosphate is
the cross-roads compound. Glucose-6-phosphate is synthesized directly from
glucose or as the end product of gluconeogenesis.
