Actions of Insulin, Glucagon, Cortisol and Epinephrine in Carbohydrate Metabolism
INSULIN
|
-
Increases the uptake of glucose by our muscle and fat cells
-
Increases the synthesis of glycogen in our muscle and liver
-
Increases fatty acid synthesis from excessive diet carbohydrate
-
Decreases fat breakdown and mobilization from our fat tissue
|
GLUCAGON
|
-
Increases glycogen breakdown in our liver
-
Increases liver glycogen-derived glucose release into our blood
-
Increases glucose manufacturing in our liver
-
Increases fat breakdown and mobilization from our fat tissue
|
EPINEPHRINE (Adrenalin)
|
-
Increases glycogen breakdown in our liver and skeletal muscle
-
Increases liver glycogen-derived glucose release into our blood
-
Increases fat breakdown and mobilization from our fat tissue
|
CORTISOL (stress hormone)
|
-
Increases muscle protein breakdown to amino acids which can circulate to the liver and be used for glucose production
-
Increases liver glycogen-derived glucose release into our blood
-
Increases fat breakdown and mobilization from our fat tissue
