The liver supplies sugar or glucose by turning glycogen into glucose in a process called glycogenolysis. Open access Under normal physiological conditions, glucagon, which is secreted by pancreatic alpha cells, works alongside insulin to regulate plasma glucose levels, including an increase in hepatic glucose production and release of glucose into circulation during hypoglycemia. Gastrointestinal glucagon, another form, . You get glucose from carbohydrates in the food you eat. This is known as insulin resistance. Phosphorylated phosphorylase clips glucose units from glycogen as glucose 1-phosphate.
