Study Notes
Effects of Hormones on Carbohydrate Metabolism
- Hormones: Glucagon, Epinephrine, Insulin
-
Source of Hormones:
- Glucagon: Pancreatic α cells
- Epinephrine: Adrenal medulla
- Insulin: Pancreatic β cells
-
Primary Targets:
- Glucagon: Liver
- Epinephrine: Muscle > Liver
- Insulin: Muscle, liver, adipose tissue
-
Effects on Metabolic Processes:
- Cyclic AMP: Increased by Glucagon and Epinephrine
- Fructose-2,6-bisphosphate: Decreased by Glucagon and Epinephrine
- Gluconeogenesis: Increased by Glucagon and Epinephrine
- Glycogen Breakdown: Increased by Glucagon and Epinephrine, decreased by Insulin
- Specific actions in muscle: Epinephrine increases glycogen breakdown in muscle, Insulin decreases glycogen breakdown in muscle.
