low, 1-2%
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.
Skeletal muscle
The liver stores 1/3 of the glycogen, while muscles will store the other 2/3.
Glycogen granules form an energy or food store in mammalian cells. When needed, the glycogen can be broken down (hydrolysed) into glucose, which is used in respiration as a source of energy for the cell. For some background see: http://www.sciencedaily.com/articles/g/glycogen.htm
Glycogen is a polysaccharide that is the principal storage form of glucose (Glc) in animal and human cells. Glycogen is found in the form of granules in the cytosol in many cell types. Hepatocytes (liver cells) have the highest concentration of it - up to 8% of the fresh weight in well fed state, or 100-120 g in an adult. In the muscles, glycogen is found in a much lower concentration (1% of the muscle mass), but the total amount exceeds that in liver. Small amounts of glycogen are found in the kidneys, and even smaller amounts in certain glial cells in the brain and white blood cells. Glycogen plays an important role in the glucose cycle
The main organ that stores the starch is called as liver. It stores about 150 grams of glycogen. Glycogen is animal starch. The total mass of muscles also store about 150 grams of glycogen.
Carbohydrates are broken down to glucose molecules which can only be stored in very small amounts. Excess glucose which are not readily used are converted into glycogen and stored in fatty tissues of the body.
total absence of glycogen in the liver may be rare but rather an abnormally low levels of glycogen is more common. This could be as a result of an impairment in any of the enzymes involved in glycogen synthesis. Now, when glycogen is low,the body will look for another source of energy. The next immediate source is fatty acid . Hence low glycogen levels will lead rapid breakdown of fatty acids which when it becomes continuous can cause weight loss.. but the brain poorly utilizes fatty acids for energy production... hence a continous depletion of glycogen levels may result in some neurological impairments..
Depends on the total number of individual muscle fibers that have been stimulated.

Glycogen- stores are optimized by consuming a high carbohydrate diet.
Skeletal muscles are the largest percentage of total muscle fibers in the human body.
