What polysaccharide is stored in the liver when excess glucose is in the bloodstream?
Glucose has many fates in the human body depending on whether the body is in a fasted or fed state. It is important to note that glucose is the main and primary compound used by all cells to produce energy. Some cells, namely nervous tissue and mature red blood cells use ONLY glucose to provide energy. If a meal with excessive carbohydrates is consumed, after digestion the excess glucose is first converted into a storage carbohydrate called glycogen. Glycogen is stored in skeletal muscles and liver cells. In muscles it serves as a ready store of energy for muscle contractions and in liver cells it can be readily reconverted into glucose and used in periods of fasting (during sleep or between meals to provide and sustain energy). However, if there is excessive glucose in the body and the muscle and liver tissues have made its maximal amount of glycogen, the excess glucose is converted to FAT! Fat (namely triacylglycerol) is made of two compounds: fatty acids and glycerol - both which can be synthesized from glucose breakdown. NOTE: Fatty acids, a main component of triacylglycerol are made from a compound called acetyl CoA. Under normal circumstances glucose is converted to acetyl CoA, but it enters a pathway in cells called the Krebs Cycle where it is degraded to produce energy. However, when there is excessive glucose and the body has already made its fill of glycogen, glucose is broken down to acetyl coA in the liver where it goes to produce fatty acids and subsequently fat! Exactly how is this done? For the biochemists out there: Malonly CoA is the direct precursor for fatty acid synthesis. Acetyl coA is converted to malonly coA via the enzyme acetyl coA carboxylase - this is the committed step in fatty acid synthesis. This enzyme is activated by high amounts of citrate, a by product of the Krebs Cycle. So an excessive amounts of glucose after maxed out glycogen production = high acetyl coA + high citrate. High citrate activates acetyl coA carboxylase which commits acetyl coA to fat production via synthesis of malonyl coA.

How is sugar digested in the human body?
When sugar is consumed, it is broken down into glucose in the small intestine. Glucose is then absorbed into the bloodstream and used by cells for energy. Any excess glucose is stored in the liver and muscles as glycogen for later use.
How is glucose transported through the body?
Glucose is transported through the body in the bloodstream. It is absorbed into the bloodstream from the intestines after digestion and released by the liver. Glucose is then taken up by cells for energy or stored for later use.
What is excess glucose stored as?
glycogen
What happens when glucose is absorbed into the bloodstream?
When glucose is absorbed into the bloodstream, it raises blood sugar levels, which triggers the release of insulin from the pancreas. Insulin helps cells take in glucose for energy or storage. If there is excess glucose, it may be stored as glycogen in the liver or converted to fat for long-term storage. Maintaining balanced blood sugar levels is important for overall health.
Glucose is stored in the liver as?
Glucose is stored in the liver as glycogen, a polysaccharide that serves as a reserve of energy. When blood glucose levels drop, glycogen can be broken down into glucose to provide a quick source of energy for the body.
How do animals store glucose?
Animals primarily store glucose in the form of glycogen in their liver and muscles. Glycogen serves as a readily accessible energy reserve that can be broken down into glucose when needed. Excess glucose can also be converted into fat for long-term energy storage.
Compound used to store excess energy reserves?
Glycogen is the compound used to store excess energy reserves in animals and humans. It is a polysaccharide made up of glucose molecules and is stored primarily in the liver and muscles.
Where is the energy I a polysaccharide stored?
The energy in a polysaccharide is stored within the chemical bonds between the glucose molecules that make up the polysaccharide. When these bonds are broken through processes like digestion, the stored energy is released and can be utilized by the body for various functions.
How is sugar digested in the human body?
When sugar is consumed, it is broken down into glucose in the small intestine. Glucose is then absorbed into the bloodstream and used by cells for energy. Any excess glucose is stored in the liver and muscles as glycogen for later use.
Is the concentration of glucose higher in intestine or in the blood?
The concentration of glucose is typically higher in the blood compared to the intestine. After consuming food, glucose is absorbed from the intestine into the bloodstream to provide energy for the body. Any excess glucose is stored in the liver or muscles for later use.
How is glucose transported through the body?
Glucose is transported through the body in the bloodstream. It is absorbed into the bloodstream from the intestines after digestion and released by the liver. Glucose is then taken up by cells for energy or stored for later use.
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.
How do the human body is glucose stored?
Glucose is stored in the body as glycogen. It is stored in the liver and in muscle tissue until it is needed, then the hormone glucagon - 'turns-the-sugar-on'- and releases the glycogen as glucose into the bloodstream.
What is excess glucose stored as?
glycogen
What happens when glucose is absorbed into the bloodstream?
When glucose is absorbed into the bloodstream, it raises blood sugar levels, which triggers the release of insulin from the pancreas. Insulin helps cells take in glucose for energy or storage. If there is excess glucose, it may be stored as glycogen in the liver or converted to fat for long-term storage. Maintaining balanced blood sugar levels is important for overall health.
How is excess glucose stored in the body and why is it stored this way?
Excess glucose is stored in the body as glycogen, primarily in the liver and muscles. This is the body's way of storing energy for later use. When the body needs energy, it can quickly break down glycogen back into glucose for fuel.
Glucose is stored in the liver and muscles as a large polysaccharide called?
Glycogen. Plants store energy in starch.... Mammals store their excess energy in glycogen.
