By beta cells in the pancreas.
Rating Newest Oldest. Best Answer: Insulin is a hormone produced by beta cells in the pancreas. It has three important functions:1 Allow glucose to pass into cells, where it is used for energy. Suppress excess production of sugar in the liver and muscles. Suppress breakdown of fat for energy. Production of Insulin in the Body The creation of insulin in the beta cells of the pancreas is a two step procedure. Beta cells first produce preproinsulin. Preproinsulin is cleaved to create proinsulin, which is further cleaved to produce equal amounts of insulin and C-peptide. However, since 1983, a product called biosynthetic human insulin has been available. This insulin does not come from human pancreases; it is produced in a laboratory by introducing a synthetic (man-made) human gene into bacteria or yeast. MainPlaceHolder. Insulin is a hormone, a chemical messenger in the body. Insulin is produced in the pancreas. It is needed to allow sugars (glucose) from food to enter cells. There, sugar is used to produce the energy needed for the cells to work properly Continue ReadingPatient Guide to Insulin: About Diabetes. Insulin is a hormone made by the pancreas that allows your body to use sugar (glucose) from carbohydrates in the food that you eat for energy or to store glucose for future use. Insulin helps keeps your blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia). If you have more sugar in your body than it needs, insulin helps store the sugar in your liver and releases it when your blood sugar level is low or if you need more sugar, such as in between meals or during physical activity. Insulin (from the Latin, insula meaning island) is a peptide hormone produced by beta cells in the pancreas. It regulates the metabolism of carbohydrates and fats by promoting the absorption of glucose from the blood to skeletal muscles and fat tissue and by causing fat to be stored rather than used for energy. Insulin is produced in the pancreas and released when any of several stimuli are detected. These stimuli include ingested protein and glucose in the blood produced from digested food. Carbohydrates can be polymers of simple sugars or the simple sugars themselves.

If your body does not produce enough insulin or your cells are resistant to the effects of insulin, you may develop hyperglycemia (high blood sugar), which can cause long-term complications if the blood sugar levels stay elevated for long periods of time. If you have more sugar in your body than it needs, insulin helps store the sugar in your liver and releases it when your blood sugar level is low or if you need more sugar, such as in between meals or during physical activity.
