when would glycogen need to be converted back to glucose
Glycogen After a meal has been digested and glucose levels begin to fall, insulin secretion is reduced, and glycogen synthesis stops. When it is needed for energy, glycogen is broken down and converted again to glucose. Glycogen phosphorylase is the primary enzyme of glycogen breakdown. For the next 8â€“12 hours, glucose derived from liver glycogen is the primary source of blood glucose used by the rest of the body for fuel.
