What is the difference between liver glycogen and muscle glycogen?

Liver glycogen has low glycogenin content as compared to muscle glycogen..

liver glycogen responds to glucagon but muscle glycogen responds to catecholamines..

liver glycogen is used for the maintenance of blood glucose levels, but muscle glycogen is used for the supply of energy to the muscles

liver glycogen can be completely broken down to glucose because of the presence of glucose 6 phosphatase, which does not occur in the muscles
