BIOL 3070 Lecture Notes - Lecture 24: Anabolism, Glycogen, Glut4
Document Summary
Lecture 24: hormonal influence on the metabolism; insulin and glucagon, endocrine function of the pancreas: Islets of langerthans produce three different hormones which are placed in an anatomical position that allows them to sense the change in the glucose of the blood: beta islet: insulin, alpha islet: glucagon. Insulin: released by the beta islet cells into the blood when the glucose levels are high to stimulate the uptake of glucose in muscle and adipose tissue. Increased uptake in the liver would be indirectly: glycogenesis would increase in liver and muscle and decrease in glycogenolysis, gluconeogenesis would decrease (production of glucose from molecules other than carbohydrates such as carbon skeleton of a. a) Increase in lipogenesis from glucose due to its abundance: uptake of fatty acids and triglycerides would increase by the fat cells, decrease in lipolysis, decrease in ketone bodies. Increase uptake of a. a by muscle and liver. Increase protein synthesis and decrease in protein degradation.
