Exam 3 -Insulin= glucose Cellular uptake Glycogen -Glucagon= Stimulates glycogenolysis and gluconeogenesis -Epinephrine -increases metabolic rate, (liver and muscle) and activates enzymes that convert glycogen to glucose -Thyroid hormone= increases metabolic rate, and accelerates all reactions -Leptin= acts by binding to leptin receptors in the hypothalamus, actuating appetite-suppressing (anorexigenic systems) -Cortisol= ensures that the brain has an adequate supply of glucose Muscle protein amino acids glucose brain (gluconeogenesis) Fats Fatty acids 1. Provide energy for gluconeogenesis 2. Fatty acids are an alternative energy source for the tissues so the brain can have the glucose GI tract -Secretin= inhibits stomach, stimulates bicarbonate secretion by cells in bile ducts and pancreas -CCK= causes gallbladder contraction, stimulates acinar cells in pancreas to secrete enzymes -Gastric inhibitory peptide (GIP)= inhibits stomach secretion and motility via somatostatin -Gastrin= secreted by G-cells stimulates stomach secretion, motility -smell of food vagus nerve Enteric Nervous system -Enterogastric reflex= inhibition of stomach by neural reflex from small intestine -Meissner’s= submucosal -Auerbach’s= myenteric plexuses
