Answer:
glucose in blood and glycogen stored in muscles.
Explanation:
Glycogen is found in most cell types, however, the largest reserves are in the liver and skeletal muscle. In muscle, glycogen is used by the muscle cell itself (fiber) and is not exported to other locations. In these cases, the glycogen molecule breaks down when there is very intense activity and is used as a source of energy.
Glucose is one of the simplest carbohydrates (monosaccharide). It is from these monosaccharides, glucose, fructose and galactose that all other carbohydrates are formed. Because glucose is our body's main energy source, all carbohydrates are broken down by specific enzymes into smaller molecules. Glucose stays in the blood and provides a lot of energy for practical activities.
