"WebGlucose is either cleaved from the glycogen molecule or enters the cell individually and is phosphorylated to glucose-6-phosphate by converting ATP to ADP with the help of the enzyme hexokinase/glucokinase. The phosphorylation of glucose serves two purposes. First, it makes the glucose molecule more reactive and ready for other reactions. " - Formation of glucose from glycogen
