Chapter 41 1. Anabolism: insulin, anabolic steroids. Available foodstuffs (in blood), glucose, amino acids, free fatty acids (liver can convert amino acids and free fatty acids into ketones) stored foodstuffs (in cells), glycogen, proteins, triglycerides. 2. Catabolism: glucagon, epinephrine, cortisol. Stored foodstuffs (in cells), glycogen, proteins, triglycerides available foodstuffs (in blood), glucose, amino acids, free fatty acids. 3. Pancreas: exocrine and endocrine. Exocrine: released digestive juices through a duct to the duodenum. Endocrine: release hormones into the blood. 4. Islets of Langerhans: a key player in the endocrine systems control of metabolism is the pancreas. Alpha Cells: glucagon. Beta Cells: insulin and amylin. Delta Cells: somatostatin. F Cells: pancreatic polypeptide. 5. Glucagon: causes cells to release stored food into blood; increases blood glucose. 6. Insulin: allows cells to take up glucose from blood; lowers blood glucose. Released in biphasic manner; 1st phase peaks at 3-5 min, 2nd phase begins at 2 min and continues ~60 min or until stimulus stops. 7. Amylin: slows glucose absorption in small intestine; suppressed glucagon secretion (lowers blood glucose). 8. Somatostatin: decreased GI activity; suppresses glucagon and insulin secretion.
