Glucagon alone can not stimulate production of PEPCK(phosphoenolpyruvate carboxykinase) rate limiting enzyme in Gluconeogenesis,rather it requires permissive action of cortisole for doing so....on the other hand cortisol and grothhormone can stimulate gluconeogenesis by their own...
so if we remove source of glucagon ; GH & Cortisol r still their to carry out gluconeogenesis..
but if we remove ant pituitary...glucagon is helpless...it can not produce PEPCK by it own....
