AP Biology: Big Idea #2 Glucose and regulation of metabolism
Metabolism Review AP Biology: Big Idea #2 Glucose and regulation of metabolism
2
Low calorie sweeteners?
How could they cause weight gain if they don’t add calories? so-sweet-side-effects-of-artificial-sweeteners Learning goals: What is an opinion paper in a journal? How does the brain regulate appetite?
3
Glucose Regulation Physiology challenge:
Volunteers from physiology to draw feedback loop: Part of the loop that responds to digestion of candy from a psych bag. Part of the loop that responds to forgetting to eat breakfast because you got up late and don’t want to miss your AP bio test!
5
Mechanism of insulin
6
Terms Glycogen synthase Glucagon Gluconeogenesis
7
What actually causes? Stimulation of glucagon release?
Amino acids & low blood glucose Inhibition of glucagon release? Blood glucose & insulin Stimulation of insulin release? Glucose transported into beta cellchange in calcium levelsrelease of insulin granules Inhibition of insulin release? Presence of glucagon inhibits insulin release
8
Role of Dietary Fiber in Glucose and Cholesterol Regulation
Soluable Fiber Forms a gel matrix Inhibits absorption of fatty acids; lowers LDL Inhibits absorption of glucose Insoluable Fiber Allows for movement of materials through digestive system Fills you up and foods with high fiber tend to be less energy dense
9
Diabetes Type 1 Type 2 Make a Venn Diagram to compare and contrast: cause, mechanism, and treatment for Type 1 and Type 2 diabetes. Obesity Epidemic: In what ways is this medical issue a societal issue?
10
Diabetes Journal Club Discussion of literature and understanding cause and treatments of Type 1 & Type 2 diabetes. Prepare ahead of time!
