The carbohydrate substrate described is glycogen. It is a highly branched molecule composed of glucose units in chains of about 10-20 glucose units per branch. Glycogen serves as a storage form of energy in animals, particularly in liver and muscle cells.
After being absorbed in the small intestine, glucose enters the bloodstream and is transported to the liver. The liver releases glucose into the bloodstream as needed, and it travels to the leg muscle cells through the circulatory system. Once in the muscle cell, glucose is used as an energy source through cellular respiration.
Glycogen is the main energy storage molecule found in liver and muscle cells. It is a polysaccharide made up of glucose units and serves as a readily available source of energy during periods of high energy demand, such as exercise or fasting.
Glycogen is called a polysaccharide because it is composed of long chains of glucose molecules bonded together. It serves as a primary form of energy storage in humans, particularly in the liver and muscle tissues. When energy is needed, glycogen can be broken down into glucose to be utilized by the body.

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
* 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.

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
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.
Glucose
The Cori cycle is metabolic interaction between the liver and muscle tissue. gluconeogenesis is occurring in the liver while glycolysis is happening in the muscle tissue. The two fates of the glucose undergoing glycolysis in the muscle tissue is ultimate breakdown into lactate and alanine.
