Role of Hormones in Homeostasis of Blood Glucose Levels



Insulin

 

Increases glycogenesis and lipogenesis and decreases glycogenolysis and gluconeogenesis

 

Lowering of blood glucose level

 

Epinephrine (adrenaline)

 

Antagonizes the action of insulin, stimulates glycogenolysis by activating phosphorylase

 

Increases blood glucose levels

 

Glucagon

 

Stimulates glycogenolysis by activating liver phosphorylase and also increases gluconeogenesis

 

Increases blood glucose levels

 

Adrenal cortical hormone

 

Stimulates gluconeogenesis prevents uptake of glucose by tissues

 

Increases blood glucose levels

 

Anterior pituitary hormone

Lipolysis and suppression of uptake of glucose by tissues

Increases blood glucose levels

 

(ACTH, GH) thyroid hormones

 

Enhances absorption of glucose from intestine and glycogenolysis in liver.

Enhances metabolism of glucose

Rise in blood glucose level is transient
