Because only beta cells, created in asmall portion of your pancreas, are capable of doing so. Certain cells have certain purposes, and finger cells aren't set up to be producers.
because the gene to make insulin isn't expressed
Insulin is made in the pancreas, not by blood cells. They have other jobs to do.
no one knows :P
Specialized pancreas cells, called beta cells, produce and release insulin. Insulin plays a crucial role in regulating blood sugar levels by promoting the uptake of glucose from the blood into cells for energy utilization or storage.
Insulin is not produced by skin cells.
Insulin-independent cells are primarily muscle cells and nervous system cells. These cells do not rely on insulin to take up glucose for energy. Instead, they have insulin-independent glucose transporters that allow them to take in glucose from the bloodstream without the need for insulin.
Insulin formed by the Golgi apparatus in insulin-producing cells leaves those cells by exocytosis. This process involves the insulin-containing vesicles fusing with the cell membrane and releasing insulin into the bloodstream.
The pancreas produces a variety of hormones, two being insulin and glucagon, these hormones are produced by groups of cells called the islets of langerhans.
The beta cells of the pancreas produce insulin and C-peptide, a byproduct of insulin. Source: Wikipedia
Bacterial cells are commonly used in biotechnology to produce insulin using exogenous DNA. The exogenous DNA encoding for human insulin is introduced into the bacterial cells, which then serve as a host to produce the insulin protein through the process of genetic engineering.
the cells called islets of langerhans are inside the pancreas. there are 5 types of cellgs within the islets of langerhans. The alpha cells produce glucagon, the beta cells produce insulin, delta cells make somatostatin (a general inhibitory hormone), and the last two types of cells, PP cells and D1 cells, little is known about what they do. The Islet of Langerhans cells are most well-known for the production and secretion of insulin.
Hi!! Diabetes occur either due to Insulin deficiency (Pancreas do not make enough Insulin) or Insulin resistance ( Pancreatic cells do not respond to Insulin normally) or both. Thus body cannot move sugar into fat, liver and muscle cells to be stored as Energy. I hope I have answered your question.
