Can glycogen in skeletal muscle be used to supply blood glucose?
Wiki User

Muscle cells lack the enzyme glucose-6-phosphatase, which is required to pass glucose into the blood, so the glycogen they store is destined for internal use and is not shared with other cells. (This is in contrast to liver cells, which, on demand, readily do break down their stored glycogen into glucose and send it through the blood stream as fuel for the brain or muscles).

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
Which type of glucose is not degraded in muscle?
according to what i read online it's the blood glucose, as the muscle leaves this blood for the brain use, because brain doesn't store glucose or glycogen as liver and muscle, and the only supply of glucose to brain is via blood glucose
A skeletal muscle's blood supply is generally best described as?

What does the Nerve Supply to a Skeletal Muscle do?
nothin
What type of muscle needs a constant supply of ATP?
Skeletal Muscles
The liver can supply the skeletal muscles with energy in the form of free glucose but the skeletal muscles cannot supply the liver with energy in the form of free glucose?
No. Unlike skeletal muscles, the liver contains an enzyme known as glucose 6-phosphatase that can remove the phosphate groups and produce free glucose.
What tissues have the best blood supply?
Skeletal Muscle
What organ relies most critically on a steady supply of glucose?
That would be the liver. The liver stocks glucose as glycogen which can be broken down to glucose.
What stores glycogen in a cell?
If your body does not have any use for the glucose, it is converted into glycogen and stored it in the liver and muscles as an energy reserve. Your body can store about a half a day's supply of glycogen. If your body has more glucose than it can use as energy, or convert to glycogen for storage, the excess is converted to fat.
How does the liver control glycogen?
* Glycogenesis - the conversion of excess glucose into glycogen as a cellular storage mechanism; this prevents excessive osmotic pressure buildup inside the cell * Glycogenolysis - the breakdown of glycogen into glucose, which provides a glucose supply for glucose-dependent tissues. * Gluconeogenesis - de novosynthesis of glucose molecules from simple organic compounds. an example in humans is the conversion of a few amino acids in cellular protein to glucose.
Does cardiac muscle have more mitochondria and depend less on a continual supply of oxygen than does skeletal muscle?
no
Why are Motor nerves that supply skeletal muscle the last to be inhibited?
Because the nerve supply for muscles are mixed
