Glycogen Flashcards
(22 cards)
Acts as a primer in glycogen synthesis
Glycogenin
Synthesis of glycigen
Glycogenesis
Breakdown of glycogen
Glycogenolysis
Synthesis of glycogen from jon carbohydrate sources
Glyconeogensis
Limiting enzyme of glycogen metabolism
Transferases
By weight glycogen is more in
Liver
By percentage glycogen is more in
Muscles
Straight chains have
a 1–> 4 bonds
Branching point has
a 1–>6 bond
Adds glucose residue to the non reducing end of the primer
Glycogen synthase
End product of liver glycogen
Free glucose
End product of muscle glycogen
Glucose 6-phosphate
Any anabolic pathway occurs in
Cytoplasm
In glucogenesis, glucose 6P is converted to glucose 1 phosphate by what enzyme?
Mutase
Glucose 1 phosphate is converted to UDP glucose by what enzyme?
UDP glucose Pyro-Phosphorylase
All catabolic pathways are activated by
Glucagon
First enzyme that breaksdown of glycogen (1-4 bonds)
Glycogen Phosphorylase
Four glucose residues
Likit dextrim
Transfers three glucose residues to the neighboring straight chain
Glucan Transferase
Breaks the last glucose residue (1-6 bond)
Debranching enzyme
Glycogen synthase is activated by what hormone
Insulin
When fasting, cAMP: increases or decreases
Increases
