Fat and amino acids can enter citric acid cycle another way Pancreatic hormones play a major role in glucose regulation Pancreas next to small intestine Duodenum is the last place that digestion occurs (a lot of juices from pancreas are released to duodenum) Pancreas has islet of Langerhans - there are endocrine alpha and beta cells Islet of Langerhans o Releases insulin and glucagon Glucagon (alpha cells) o Released when blood sugar low o Increases: Glycogenolysis (glycogen to glucose) Gluconeogenesis – turns shit into glucose Ketogenesis – brain runs on ketone bodies ( diabetes 1 patients ) o Released when hungry Insulin (Beta cells) o Released when blood sugar high 44

Once insulin is released….. Insulin works on skeletal muscle and fat cells GLUT4 takes more glucose in Without insulin, glucose cant enter cell o Diabetes 2- pancreas is working like crazy to release insulin but body does not respond Diabetes 1- self inject insulin Diabetes 2- does not self-inject insulin because they have too much Fasted state metabolism o Glucagon is high o Bile acid is low o Gluconeogenesis increases 47
