Muscle glycogen is an important fuel for contracting skeletal muscle during prolonged
strenuous exercise, and glycogen depletion has been implicated in muscle fatigue. It is also
apparent that glycogen availability can exert important effects on a range of metabolic and
cellular processes. These processes include carbohydrate, fat and protein metabolism during
exercise, post-exercise glycogen resynthesis, excitation--contraction coupling, insulin action
and gene transcription. For example, low muscle glycogen is associated with reduced muscle
glycogenolysis, increased glucose and NEFA uptake and protein degradation, accelerated
glycogen resynthesis, impaired excitation--contraction coupling, enhanced insulin action and
potentiation of the exercise-induced increases in transcription of metabolic genes. Future
studies should identify the mechanisms underlying, and the functional importance of, the
association between glycogen availability and these processes.

The primary function of insulin is?
Stimulates conversion of excess glucose to glycogen
How is glycogen present in the muscle cell?
Glycogen is the storage form of glucose in the muscle cell. Glycogen can be used for energy.
Is glycogen primarily stored in muscle tissue?
Glycogen is stored in muscle tissue and the liver.
What is Muscie Glycogen?
Muscle Glycogen is basically the storage of carbohydrates in the body. Muscle glycogen is what fuels the body and is a necessity for a proper workout.
Where is glycogen?
Glycogen is stored in a liver or muscle cell.
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
Where is glycogen stored?
Glycogen is stored in a liver or muscle cell.
Is muscle glycogen the primary fuel for endurance exercises?
Yes, muscle glycogen is a primary fuel source for endurance exercises such as long-distance running and cycling. It is stored in muscle tissue and can be rapidly broken down to provide energy during prolonged, low to moderate intensity activities. However, for longer endurance events, the body may also utilize fat stores as a fuel source.
What type of polysaccharide is found in potatoes?
Starch is found potatoes, not Glycogen. Glycogen is the plant equivalent of animal glycogen. A potato has starch but no glycogen; muscle cells have glycogen but no starch. The starch we eat is broken into glucose in the stomach/small intest and then reassembled in the muscle cells as glycogen.
What is the function of the trachealis muscle?
The primary function of the trachealis muscle is to constrict the trachea, allowing air to be expelled with more force e.g. during coughing.
Where do we have a small store of glycogen?
Glycogen is primarily stored in the liver as well as in skeletal muscle, kidney and heart. A single muscle cell therefore is also a small store of glycogen.
Does Muscle glycogen cause muscle contraction?
no, lactic acid does
