Low insulin:glucagon ratio (IGR) stimulates mobilization of stored nutrients, increases glycogenolysis and gluconeogenesis, and promotes the breakdown of adipose tissue into free fatty acids and glycerol.
Decreases Insulin/glucagon ratio shows the fasting stage. Glucokinase, Hexokinase, and phosphofructokinase are glycolytic.
Only gluconeogenic is glucose-6-phosphatase.
