Animals store glucose in the form of glycogen in their liver and muscle cells. Glycogen is a polysaccharide that serves as a readily accessible energy reserve, allowing for quick mobilization during periods of increased energy demand, such as exercise. When glucose is needed, glycogen can be broken down into glucose molecules through a process called glycogenolysis.
GLYCOGEN
Liver cells store chains of glucose in a molecule called glycogen, while muscle cells store glucose in the form of glycogen as well. Glycogen acts as a reserve of energy that can be broken down into glucose when needed for energy production.
Glycogen
No, muscle cells do not release glucose into the blood. Instead, they take up glucose from the blood to use as fuel for energy production during muscle contraction. Glucose release into the blood is primarily regulated by the liver through a process called gluconeogenesis.
Muscle glycogen stores can account for up to 1-2% of muscle mass, whereas liver glycogen stores can accommodate around 5-6% of liver mass. The total glycogen storage capacity in the liver is typically higher than in muscle due to the liver's role in maintaining blood glucose levels for the body.

Glycogen is a highly branched arrangement of glucose molecules found in liver and skeletal muscle cells. It serves as a storage form of glucose, which can be quickly broken down to provide energy when needed by the body.
* Insulin - released by pancreas - encourages liver and muscle cells to absorb glucose from the blood; stimulates the conversion of glucose ----> glycogen in liver/muscle cells.
Excess glucose is stored in liver cells and muscle cells in the form of glycogen. When blood glucose levels are high, insulin signals these cells to take up glucose and convert it into glycogen for storage. This glycogen can later be broken down back into glucose when energy is needed.

Glycogen
Insulin signals blood cells like liver and muscle cells. These are used to accelerate the conversion of glucose to glycogen that's stored in the liver. Glucagon attach themselves to liver cells telling them to convert glycogen to glucose and to release glucose into the blood.

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.
