  2. Cahill cycle - Wikipedia

    en.wikipedia.org/wiki/Cahill_cycle

    The Cahill cycle, also known as the alanine cycle or glucose-alanine cycle, [1] is the series of reactions in which amino groups and carbons from muscle are transported to the liver. [2] It is quite similar to the Cori cycle in the cycling of nutrients between skeletal muscle and the liver. [ 1 ]

  3. Cori cycle - Wikipedia

    en.wikipedia.org/wiki/Cori_cycle

    Cori cycle. The Cori cycle (also known as the lactic acid cycle), named after its discoverers, Carl Ferdinand Cori and Gerty Cori, [1] is a metabolic pathway in which lactate, produced by anaerobic glycolysis in muscles, is transported to the liver and converted to glucose, which then returns to the muscles and is cyclically metabolized back to lactate.

Atom balance is maintained by the two phosphate (P i) groups: Each exists in the form of a hydrogen phosphate anion, dissociating to contribute ...

  5. Gluconeogenesis - Wikipedia

    en.wikipedia.org/wiki/Gluconeogenesis

    The contribution of Cori cycle lactate to overall glucose production increases with fasting duration. [14] Specifically, after 12, 20, and 40 hours of fasting by human volunteers, the contribution of Cori cycle lactate to gluconeogenesis was 41%, 71%, and 92%, respectively.

  6. Glucogenic amino acid - Wikipedia

    en.wikipedia.org/wiki/Glucogenic_amino_acid

    As an example, consider alanine. Alanine is a glucogenic amino acid that the liver's gluconeogenesis process can use to produce glucose. Muscle cells break down their protein when their blood glucose levels fall, which happens during fasting or periods of intense exercise. The breakdown process releases alanine, which is then transferred to the ...

  7. Transaminase - Wikipedia

    en.wikipedia.org/wiki/Transaminase

    In similar manner, in muscles the use of pyruvate for transamination gives alanine, which is carried by the bloodstream to the liver (the overall reaction being termed glucose-alanine cycle). Here other transaminases regenerate pyruvate, which provides a valuable precursor for gluconeogenesis.

  9. 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]
