Regulation of Glucose Clinical Chemistry Review 83
HORMONE ACTION RELATIVE IMPORTANCE
Decreases glucose levels
Insulin Responsible for entry of glucose into cells. Increases glycogenesis. Primary
Increases glucose levels
Glucagon Stimulates glycogenolysis & gluconeogenesis. Inhibits glycolysis. Primary
Cortisol Insulin antagonist. Increases gluconeogenesis. Secondary
Epinephrine Promotes glycogenolysis & gluconeogenesis. Secondary
Growth hormone Insulin antagonist. Secondary
Thyroxine Increases glucose absorption from GI tract. Stimulates glycogenolysis. Negligible
