| Questão | Responda |
| What factors regulate Glycogen Phosphorylase (breaks down alpha 1-4 bonds)? | Stimulate- Adrenaline, Glucagon, Ca. Inhibit- Insulin. |
| What enzyme breaks down Alpha 1-4 bonds? | Glycogen Phosphorylase (requires Pi) |
| What breaks down alpha 1-6 bonds? | Glycogen debranching enzyme. |
| What is Glycogenolysis? | Breakdown of Glycogen |
| Where 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) |
| What is Glycogen? | Polymer of Glucose Molecules which is formed by both alpha 1-4 and alpha 1-6 bonds. |
| What are alpha 1-4 bonds? | Cause linear chain of glucose, which are broken down by the enzyme Glycogen Phosphorylase (requires Pi) |
| What are alpha 1-6 bonds? | Causes branching of Glucose Molecules, which are broken down by Debranching Enzymes. |
| How 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. |
