  2. Blood sugar regulation - Wikipedia

    en.wikipedia.org/wiki/Blood_sugar_regulation

    The cells release the glucose into the bloodstream, increasing blood sugar levels. Hypoglycemia, the state of having low blood sugar, is treated by restoring the blood glucose level to normal by the ingestion or administration of dextrose or carbohydrate foods. It is often self-diagnosed and self-medicated orally by the ingestion of balanced meals.

  3. Insulin signal transduction pathway - Wikipedia

    en.wikipedia.org/wiki/Insulin_signal...

    The second phase is a slow release of newly formed vesicles that are triggered regardless of the blood sugar level. Glucose enters the beta cells and goes through glycolysis to form ATP that eventually causes depolarization of the beta cell membrane (as explained in Insulin secretion section of this article). The depolarization process causes ...

  4. A 2019 meta-analysis found no positive effect of sugar consumption on mood but did find an association with lower alertness and increased fatigue within an hour of consumption, known as a sugar crash. [355] Sugar can however lead to jump in blood sugar levels, causing temporary hyperactivity even if it does not cause clinical hyperactivity. [356]

  5. Insulin receptor - Wikipedia

    en.wikipedia.org/wiki/Insulin_receptor

    The insulin receptor (IR) is a transmembrane receptor that is activated by insulin, IGF-I, IGF-II and belongs to the large class of receptor tyrosine kinase. [5] Metabolically, the insulin receptor plays a key role in the regulation of glucose homeostasis; a functional process that under degenerate conditions may result in a range of clinical manifestations including diabetes and cancer.

  6. Reticular cell - Wikipedia

    en.wikipedia.org/wiki/Reticular_cell

    A reticular cell is a type of fibroblast that synthesizes collagen alpha-1(III) and uses it to produce extracellular reticular fibers.Reticular cells provide structural support, since they produce and maintain the thin networks of fibers that are a framework for most lymphoid organs.

  7. Insulin - Wikipedia

    en.wikipedia.org/wiki/Insulin

    Beta cells are sensitive to blood sugar levels so that they secrete insulin into the blood in response to high level of glucose, and inhibit secretion of insulin when glucose levels are low. [10] Insulin production is also regulated by glucose: high glucose promotes insulin production while low glucose levels lead to lower production. [ 11 ]

  8. Glucokinase - Wikipedia

    en.wikipedia.org/wiki/Glucokinase

    Glucokinase has been discovered in specific cells in four types of mammalian tissue: liver, pancreas, small intestine, and brain. All play crucial roles in responding to rising or falling levels of blood glucose. The predominant cells of the liver are the hepatocytes, and GK is found exclusively in these

  9. Beta cell - Wikipedia

    en.wikipedia.org/wiki/Beta_cell

    Beta cells (β-cells) are specialized endocrine cells located within the pancreatic islets of Langerhans responsible for the production and release of insulin and amylin. [1] Constituting ~50–70% of cells in human islets, beta cells play a vital role in maintaining blood glucose levels. [2] Problems with beta cells can lead to disorders such ...
