  2. Glucose cycle - Wikipedia

    en.wikipedia.org/wiki/Glucose_cycle

    The glucose cycle can occur in liver cells due to a liver specific enzyme glucose-6-phosphatase, which catalyse the dephosphorylation of glucose 6-phosphate back to glucose. Glucose-6-phosphate is the product of glycogenolysis or gluconeogenesis, where the goal is to increase free glucose in the blood due body being in catabolic state. Other ...

  3. Liver cytology - Wikipedia

    en.wikipedia.org/wiki/Liver_cytology

    Cytology is the name given to the branch of biology that deals with the formation, structure and functionality of the cells. [1] Liver cytology specializes in the study of liver cells. The main liver cells are called hepatocytes; however, there are other cells that can be observed in a liver sample such as Kupffer cells (macrophages). [2]

  4. Glycogen - Wikipedia

    en.wikipedia.org/wiki/Glycogen

    Liver glycogen stores serve as a store of glucose for use throughout the body, particularly the central nervous system. [4] The human brain consumes approximately 60% of blood glucose in fasted, sedentary individuals. [4] Glycogen is an analogue of starch, a glucose polymer that functions as energy storage in plants.

  5. Glucose paradox - Wikipedia

    en.wikipedia.org/wiki/Glucose_paradox

    The lactate is then taken and converted by the liver, forming the material for liver glycogen. The majority of the body's liver glycogen is produced indirectly, rather than directly from glucose in the blood. Under normal physiological conditions, glucose is a poor precursor compound and use by the liver is limited. [2] [3]

  6. Glucose 6-phosphate - Wikipedia

    en.wikipedia.org/wiki/Glucose_6-phosphate

    When the body needs glucose for energy, glycogen phosphorylase, with the help of an orthophosphate, can cleave away a molecule from the glycogen chain. The cleaved molecule is in the form of glucose 1-phosphate, which can be converted into G6P by phosphoglucomutase.

  7. Glycogenesis - Wikipedia

    en.wikipedia.org/wiki/Glycogenesis

    Glycogenesis is the process of glycogen synthesis or the process of converting glucose into glycogen in which glucose molecules are added to chains of glycogen for storage. This process is activated during rest periods following the Cori cycle, in the liver, and also activated by insulin in response to high glucose levels. [1]

  8. Glycolysis - Wikipedia

    en.wikipedia.org/wiki/Glycolysis

    d -Glucose + 2 [NAD] + + 2 [ADP] + 2 [P] i 2 × Pyruvate 2 × + 2 [NADH] + 2 H + + 2 [ATP] + 2 H 2 O Glycolysis pathway overview The use of symbols in this equation makes it appear unbalanced with respect to oxygen atoms, hydrogen atoms, and charges. Atom balance is maintained by the two phosphate (P i) groups: Each exists in the form of a hydrogen phosphate anion, dissociating to contribute ...

  9. Lobules of liver - Wikipedia

    en.wikipedia.org/wiki/Lobules_of_liver

    In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale. The hepatic lobule is a building block of the liver tissue , consisting of a portal triad, hepatocytes arranged in linear cords between a capillary network, and a central vein .
