What is the difference in the use of muscle glycogen and liver glycogen?

Liver glycogen can easily produce glucose by glycogenolysis and that can be used by local cells for respiration.
but as muscle cells lack Glucose-6-phosphate , in muscle glycogen cannot get transferred to glucose and hence cannot be used locally.

∙ 14y agoGlycogen is broken down into Glucose-6-phosphate units. ?When your blood sugar is low, the liver breaks down its glycogen to provide the body with energy; thus, the liver has an enzyme called glucose-6-phosphotase that can turn glucose-6-phosphate into glucose. ?The glucose can enter the circulation, and your body is saved from starvation.
When the muscle breaks down its glycogen, it wants to keep its glucose for itself (because it wants to use it for energy if you are lifting something or running around or whatever). ?It does not want the glucose to leave the muscle cells, so it has no glucose-6-phosphotase enzyme. ?Without this enzyme, the glucose-6-phosphate is trapped in the muscle cells, so the muscles alone get to use it.

The signal transduction pathway in animal cells that use epinephrine?
activates the breakdown of glycogen in liver and skeletal muscle cells.
What do all muscles have a store, of which used for fuel?
Glucose can be used immediately as fuel, or can be sent to the liver and muscles and stored as glycogen. During exercise, muscle glycogen is converted back into glucose, which only the muscle fibers can use as fuel.
How is excess glucose stored in liver and muscle cells?
After a meal, as blood glucose rises, the pancreas is the first organ to respond. It releases the hormone insulin, which signls the body's tissues to take up surplus glucose. Muscle and liver cells use some of this excess glucose to build glycogen.
What stores energy for short-term use?
Glycogen which is found in the liver.
Can glycogen in skeletal muscle be used to supply blood glucose?
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).
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
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 glucose work in the liver?
The liver works by producing bile and removing toxins from the blood. It converts glycose into glycogen and even keeps your body core temperature at 27 degrees celsius. It works with the stomach, gallbladder, and small intestines. If your liver fails, toxins build up in your blood stream and you almost certainly die (without a transplant of course).
Glycogen is stored in the body for future use If it is drawn upon it will?
be depleted from the liver after several days
Polysaccharide in animals that stores energy?
my answer is always correct :) its glycogen and for Plato users the answer is A
Is glycogen stored in muscle cells is used primarily to provide glucose for red blood cells?
Doubtful. One would think that any glycogen stored in muscle cells would be producing mitochondrial ATP for use in the sarcomere, the muscle contraction unit.
What are the Glycogen sources?
Any type of food does not contain glycogen. Starch and carbohydrate will become glucose after entering our body. The glucose is then converted into glycogen by insulin. For what purpose? To maintain the blood sugar level. If the blood sugar level decreases, glucagon will convert the glycogen into glucose again.
