Answer:
Glycogen stored in muscles
Glycogen stored in the liver cells
Glucose that is available in the bloodstream
Explanation:
Carbohydrate is the class of food in which its digestion starts in the mouth. The end product of the digestive breakdown is Glucose. Excess glucose formed is usually stored as glycogen in liver and muscle cells.
The readily available source of glucose for working muscles is glycogen that is stored in muscles which is broken down back into glucose. The liver also helps supply glucose for muscles by degrading glycogen and releasing glucose molecules into the bloodstream.
