What is the difference between liver glycogen and muscle glycogen?
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

When hummingbirds migrate why is it better for birds to store energy as fat rather than as glycogen?
What is Introduction to Glycogen Metabolism?
glycogen metabolism is the terminology used for both glycogen synthesis and glycogen degradation ,glycogenesis and glycogenolysis .both of these pathways are exactly opposite to each other because both of these pathways involve different enzymes glycogenesis is carried out by enzymes HEXOKINASE,PHOSPHOGLUCOMUTASE,UDP-GLUCOSE-PYROPHOSPHORYLASE,and GLYCOGEN SYNTHASE. glycogenolysis is carried out by enzymes GLYCOGEN PHOSPHORYLASE,PHOSPHOGLUCOMUTASE,and debranching enzyme (GLUCAN TRANSFERASE).

How does the structure of glycogen aids in its function?
glycogen contains many branches of glucose molecules and acts as a storage of energy. Glucose molecules are cut off and used for energy. Because glycogen is so widely branched, glucose can be cut off from many of the branches simultaneously instead of one at a time. If it were one at a time as would be expected in a single, straight chain, we wouldn't be able to produce as much energy as quickly.
Asked in Human Anatomy and Physiology
Tissue in body with highest glycogen content?
Glycogen are found principally in the liver. Glycogen is a polymer of glucose residues linked by α-(1,4)- and α-(1,6)-glycosidic bonds. A second major source of stored glucose is the glycogen of skeletal muscle. , muscle glycogen is not generally available to other tissues, because muscle lacks the enzyme glucose-6-phosphatase.

What effect would increased levels of glucagon have on the amount of glycogen stored in the liver?
What are the storage and quick-energy forms of carbohydrates found in animals and how are these forms structurally related to eachother?
glycogen is the major source of glucose storage in most animals. It is mainly stored in the liver. Glucose is taken up from the blood stream and transported to the liver where cells link up the glucose molecules into chains which are called glycogen. I believe most types of glycogen formation in mammals is similar, only the amount and type of branching of these glycogen storage molecules may differ. and they are related because some can travel in waves like light and sound they all can have an impact on an object
Asked in Medical Technologies
How is glycogen made?
Through condensation reactions. Glycogen is a polysaccharide. This means it is the polymer of many monosaccharides. The monomer of Glycogen is Glucose. Glucose, through condensation reactions in which water is released, joins to form the branched structure of Glycogen. This feature is beneficial in animals as it is easy to break off the individual glucose for energy through enzymes but also because polysaccharides are insoluble while monosaccharides are.

Asked in Biology
How many grams of glycogen are stored per one kilogram of the human body weight?
There is debate as to this answer. It is also hard to answer because glycogen is not stored evenly throughout the body, it is stored in the liver and the muscle tissue. Assuming a person has been eating plenty of food, namely carbs, and the glycogen levels are full most texts report the liver being able to hold 70-100 grams of glycogen and the muscles holding 200-400 grams of glycogen. The more muscles someone has and the more trained they are (athletes, etc) the more glycogen they can hold. If we say an average male is 80 kg and an average male has 350 grams of glycogen, then you have about 4.5 grams of glycogen per kg, but again it is not stored evenly so it is an unusual way of framing the question.

What role does glycogen play in animal cells?
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 most common disease in which glycogen metabolism becomes abnormal is diabetes, in which, because of abnormal amounts of insulin, liver glycogen can be abnormally accumulated or depleted.

Asked in Dieting and Weight Loss, Energy
Is the only way your body can store energy from food is in the form of body fat?
False. Your body can store energy from food for future use in two ways: 1) as fat and 2) as muscle fuel (called glycogen). Its first priority is to fill its glycogen tanks, because glycogen is the body's primary source of energy for physical activity. Once your glycogen stores are filled and the rest of the body's energy needs are covered, all the extra energy from your food will be stored as body fat.
Asked in Biology
How does the alpha differ from the beta form of glucose and why is it significant to animals?
Cellulose is a polymer composed of beta-glucose subunits. This gives rise to straight chains that are rigid. Plant cell walls have cellulose, which gives strength in their structure but it is insoluble. Glycogen, on the other hand, is a polymer composed of alpha-glucose subunits. We have lots of glycogen in our liver. When we are not eating, we break down glycogen into its glucose subunits and then use glucose to generate energy. We can store glycogen because it is soluble in water unlike cellulose. It is important for our energy storage molecule to be water soluble because it needs to be accessible to the enzymes that will break it down into glucose. Glycogen is soluble in water because the alpha-glucose is helical, with the OH groups pointing outwards. In cellulose, the beta-chains aggregate so the OH groups are not very accesible to water. Also, glycogen has many branches so there are plenty of places for the enzymes to work on when we need glucose.
