  2. Glycosome - Wikipedia

    en.wikipedia.org/wiki/Glycosome

    The membrane is a lipid bilayer. The glycogen that is found within the glycosome is identical to glycogen found freely in the cytosol. [6] Glycosomes can be associated or attached to many different types of organelles. They have been found to be attached to the sarcoplasmic reticulum and its intermediate filaments.

  3. Glycogen - Wikipedia

    en.wikipedia.org/wiki/Glycogen

    Glycogen is found in the form of granules in the cytosol/cytoplasm in many cell types, and plays an important role in the glucose cycle. Glycogen forms an energy reserve that can be quickly mobilized to meet a sudden need for glucose, but one that is less compact than the energy reserves of triglycerides . As such it is also found as storage ...

  4. Glucose transporter - Wikipedia

    en.wikipedia.org/wiki/Glucose_transporter

    Is expressed by renal tubular cells, liver cells and pancreatic beta cells. It is also present in the basolateral membrane of the small intestine epithelium. Bidirectionality is required in liver cells to uptake glucose for glycolysis and glycogenesis, and release of glucose during gluconeogenesis. In pancreatic beta cells, free flowing glucose ...

  5. Carbohydrate metabolism - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate_metabolism

    In humans, insulin is made by beta cells in the pancreas, fat is stored in adipose tissue cells, and glycogen is both stored and released as needed by liver cells. Regardless of insulin levels, no glucose is released to the blood from internal glycogen stores from muscle cells.

  6. Glucose - Wikipedia

    en.wikipedia.org/wiki/Glucose

    Liver cell glycogen can be converted to glucose and returned to the blood when insulin is low or absent; muscle cell glycogen is not returned to the blood because of a lack of enzymes. In fat cells, glucose is used to power reactions that synthesize some fat types and have other purposes. Glycogen is the body's "glucose energy storage ...

  7. Glycogenolysis - Wikipedia

    en.wikipedia.org/wiki/Glycogenolysis

    In myocytes (muscle cells), glycogen degradation serves to provide an immediate source of glucose-6-phosphate for glycolysis, to provide energy for muscle contraction. Glucose-6-phosphate can not pass through the cell membrane, and is therefore used solely by the myocytes that produce it.

  8. Polysaccharide - Wikipedia

    en.wikipedia.org/wiki/Polysaccharide

    Glycogen is found in the form of granules in the cytosol/cytoplasm in many cell types and plays an important role in the glucose cycle. Glycogen forms an energy reserve that can be quickly mobilized to meet a sudden need for glucose, but one that is less compact and more immediately available as an energy reserve than triglycerides (lipids).

  9. Glycogenin-1 - Wikipedia

    en.wikipedia.org/wiki/Glycogenin-1

    It is primary means of glucose storage in animal cells. In the human body, the two main tissues which store glycogen are liver and skeletal muscle. [ 6 ] Glycogen is typically more concentrated in the liver, but because humans have much more muscle mass, our muscles store about three quarters of the total glycogen in our body.
