- effects of high level of Glucagon? breakdown of glycogeen, fat and proteins Glycogenphosphorylase is activated: aktivating Glycogenolysis activating Gluconeogenesis slows down glycogenesis speeds up glycogenolysis
- effects of high insulin level ? Glucoseuptake and glycogen synthesis activates hexokinase --> +++ Glycolysis viel glucose 6-phosphate --> +++ glycogenese inhibits glucose 6-phosphatase --> - - - glyconeogenesis
