Firstly, glycogen is a polysaccharide of glucose (made up from lots of glucose monomers), and functions as the primary short term energy storage in animal cells (mostly in liver).
When the organism needs energy, it sends a signal (hormones: adrenaline and glucagon) to the cells of the liver, so that they would start decomposing glycogen (separating it into its smaller parts - glucose). Then glucose is secreted (thrown out) into the blood, so that other cells can use it to do work.
If you need a more scientific explanation:
When a signal molecule of adrenaline or glucagon attaches to the receptor of the glycagon containing cell, the receptor activates adenylyl cyclase (transmembrane protein), which converts ATP to cAMP (cyclic adenine monophosphate). cAMP activates protein kinase A (PKA), which activates phosphorilase kinase b, which then activates glycogen phosphorilase. Only then glycogen phosphorilase catalyses the reaction of glycogen decomposure into glucose.
What else can I help you with?
What is the energy storing polysaccharides for animals?
Glycogen
What organ in a mammal is responsible for storing glycogen?
Mainly the liver but Glycogen is also found in muscles too.
Energy storing polysaccharide of animals?
A. Glycogen just answered it on plato lol.
What is the function of glycogen granules in bacteria?
Our bodies way of storing carbohydrates.
What is the main organ for storing starch?
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.
What is the name of the polysaccharide that is used for the storage of energy in a human liver?
Glycogen is the polysaccharide used for storing energy in the liver. It is a highly branched polymer of glucose molecules and serves as a readily available energy source when needed.
Why carbohydrates are stored as glycogen?
Carbohydrates are stored as glycogen because glycogen serves as a readily accessible source of energy for the body. It is a highly branched polymer of glucose, allowing for rapid mobilization of glucose when energy is needed, such as during exercise or fasting. Storing carbohydrates as glycogen also helps to maintain blood sugar levels, ensuring a consistent energy supply for vital organs. Additionally, glycogen storage minimizes osmotic pressure compared to storing glucose directly, making it more efficient for the body.
What part of the body makes and stores energy?
The liver is responsible for making and storing energy in the form of glycogen. The muscles also store energy in the form of glycogen to be used during physical activity.
How much glycogen does the body typically store?
The human body can store between 300-500 grams of glycogen, with the liver storing about 100 grams and the muscles storing approximately 400 grams. This glycogen serves as a readily accessible energy source for the body, particularly during exercise.
Do bones provide reserves of Glycogen?
No, bones do not provide reserves of glycogen. Glycogen is stored in the liver and muscles, not in bones. Bones are primarily responsible for providing structure and support to the body, as well as producing blood cells and storing minerals like calcium and phosphorus.
Do plants use energy storage from glycogen?
no they use fructose oh and yahoo answers is better you would already have a response.
What is a glucose polymer that also serves as an energy storing polysaccharide?
Glycogen is a glucose polymer that serves as an energy-storing polysaccharide in animals. It is stored in the liver and muscles and can be quickly broken down to release glucose when energy is needed.
