Glycogenolysis
Fichas del conjunto (9)
- 1What factors regulate Glycogen Phosphorylase (breaks down alpha 1-4 bonds)?Stimulate- Adrenaline, Glucagon, Ca. Inhibit- Insulin.
- 2What enzyme breaks down Alpha 1-4 bonds?Glycogen Phosphorylase (requires Pi)
- 3What breaks down alpha 1-6 bonds?Glycogen debranching enzyme.
- 4What is Glycogenolysis?Breakdown of Glycogen
- 5Where do we store Glycogen?In Skeletal Muscle and in the Liver. Both Muscle and Liver Glycogen are broken down to Glucose-6-Phosphate, but muscle glycogen is used for ATP generation through Glycolysis, whereas liver glycogen becomes Glucose (Glucose 6 Phosphatase breaks down Glucose 6 Phosphate to Glucose)
- 6What is Glycogen?Polymer of Glucose Molecules which is formed by both alpha 1-4 and alpha 1-6 bonds.
- 7What are alpha 1-4 bonds?Cause linear chain of glucose, which are broken down by the enzyme Glycogen Phosphorylase (requires Pi)
- 8What are alpha 1-6 bonds?Causes branching of Glucose Molecules, which are broken down by Debranching Enzymes.
- 9How does branching help us?The branching, caused by alpha 1-6 bonds allows for rapid glycogen degradation as the enzymes can break down many glucose molecules simultaneously.
