1 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!

4

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 cellchange in calcium levelsrelease 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!
