Glycogenesis
Cards in this deck (6)
- 1What factors inhibit and stimulate Glycogen Synthase (form alpha 1-4 bonds)?Stimulate: Glucose-6-Phosphate, Adrenaline, Insulin. Inhibit: Glucagon, Ca
- 2What role does UDP-Glucose play? and how do we form it?UDP-Glucose is the handle used to form alpha 1-4 bonds. We form it through Uridine (UTP) and Glucose-1 Phosphate combining (through enzyme UDP-Glucose Pyrophosphoryllase) forming UDP-Glucose and 2Pi.
- 3What is Glycogenesis?Formation of Glycogen
- 4How do we form Alpha 1-4 bonds?UDP-Glucose (Uridine+2Pi) acts as the glue to form the bonds. UDP-Glucose is formed through the breakdown of UTP-Glucose by the enzyme UDP-Glucose Phosphorylase.
- 5How do we form Alpha 1-6 bonds?We form 1-6 bonds by Glycogen Synthase which activates a branching enzyme which causes the linear glucose chain to snap and reattach forming a branch.
- 6What role does Insulin play?When Insulin levels are high (High Glucose) we form glucose through Glycogenesis. When Insulin is low (Low Glucose) we form glucose through Glycogenolysis.
