Antagonistic Hormone Research Paper

Glucagon is the other hormone produced by the Islets of Langerhans. This hormone is produced by the alpha cells in the islets, which detect when blood sugar levels are too low (around 70 mg/dL) and respond by releasing glucagon. Glucagon stimulates the breakdown of stored glycogen into glucose through a process called glycogenolysis, and releases the glucose back into the bloodstream, thus raising blood sugar levels to a higher concentration. As blood glucose levels return to its equilibrium, the concentration of glucagon lowers until the time when glucose levels rise again. In reaction to this, insulin levels rise and fall with the levels of blood glucose concentration.

When food is ingested it travel along the digestive track in to the stomach. where it is broken down in to nutrients in order to be absorbed by the small intestine and inters the blood stream to travel through the circulation to all body cells. One of the nutrients is glucose. When the glucose concentration rise it get detected by the beta cells in the pancreas

The hormone which is made by the pancreas is said to be insulin that permits the body to utilize sugar from carbohydrates and its maintain energy for future use. Insulin mainly helps to maintain the sugar level in blood from getting high to low. The cells in the body require energy which can get from sugar and it cannot go directly into the cells. After eating the food, blood sugar level increases that time the cells in the pancreas will give signal to release insulin in the blood stream. Insulin after attaches to and the cell in signal will absorb sugar in the bloodstream. Insulin is termed as key which open the cell to allow the sugar into the cell and it can be used for energy.

Chronic elevated glucose in blood (hyperglycemia) with disturbances metabolism of protein, fat and carbohydrate resulting from disorder in insulin secretion, insulin action, or both. (1) Expected to increase diabetic patients by 2025 to approximately 300 million people in the worldwide (2) In ancient times it was difficult to identify diabetes as the ability of patients to heal weak, the researchers think the diabetes resulting from defect in the bladder and kidneys are the cause of diabetes.

Diabetes one, and two revolve around the hormone insulin. Insulin is produced by the pancreas and its job is to help the cells in the body absorb glucose from the blood. Once the glucose is absorbed it signals beta cells from the pancreas to secrete insulin. Insulin enables glucose to enter cells of the liver and muscle. After the glucose has entered the cells, hormones that include insulin, decided if the glucose will be used as energy, or stored as glycogen for the future. The stored glycogen is important because if you haven’t eaten and your blood sugar is low, the body can take from the stored glycogen and use it as a source of energy.

[When one has Diabetes their blood sugar levels are too high. When we eat foods that contain carbohydrates our body turns the food into glucose, sugar. The cells in our body absorb the glucose and send them into the blood stream. When the blood gets to the pancreas, beta cells recognize the glucose and release insulin into the blood stream. The insulin and glucose then exit the blood stream and go into tissues to enter the cells. The cells have receptors that insulin bind onto. The insulin opens up the cells to let the

The body regulates the blood glucose levels by producing insulin. Insulin is a chemical messenger essential for the entry of glucose into a cell. When the pancreas fails to produce insulin that is sufficient to use, the level of glucose in the blood will remain high. If to much insulin is produced, or given through medication, the level of glucose in the blood will remain low. In type 2 diabetes the cells become resistant to insulin and ignore its message to be absorbed into the cells, this is known as insulin resistance. Insulin deficit results in decreased transportation of glucose from cells in the body, hyperglycemia then arises causing to much glucose to be present in the bloodstream (Gould and Dyer, 2011: 550). The pancreas is located

There are different type of nuclear receptors, types (I-IV). Steroid hormone receptors such as the estrogen receptor is type I. Type I undergoes nuclear translocation from cytoplasm into the nucleus upon ligand activation (hormone-receptor complex). The Hormone diffuses through the cell membrane where it binds to the nuclear receptor/heat shock protein in the cytosol. Upon the hormone binding, the heat shock protein dissociates. Dimerization then takes place resulting in two homodimers where it trans-locates into the nucleus, binding to inverted repeat DNA half sites called Hormone Response Elements (HREs), found within a promotor of a gene. In the case of oestrogen, it binds to oestrogen response elements. The nuclear receptor/ DNA complex

The pancreatic hormone glucagon is a peptide secreted by the alpha cells in the islets of Langerhans, a region located in the tail of the pancreas ("Glucagon..."). Similar to the other major pancreatic hormone insulin, glucagon helps to regulate the levels of glucose in the body. While insulin works mainly to reduce high blood glucose levels, glucagon does the opposite and works to increase low blood glucose levels by seeking other sources of stored glucose in the body. When blood glucose is low—like in between meals or during exercise—alpha cells secrete glucagon into the bloodstream. The protein then travels to the liver, where it is recognized by G protein coupled receptors on the hepatocytes ("Glucagon - New World Encyclopedia"). Glucagon

In our body we have a gland called the pancreas, inside the pancreas there are small beta cells, and these are the cells that produce chemicals called insulin for our body. When we eat carbohydrate foods, the food are broken down into glucose, the glucose then travels to the bloodstream so that it can be used as energy for the different cells around the body. Cells such as the muscle cells, the brain cells and fat cells. Now the job of the insulin is to remove the glucose from the blood and change it

Diabetes Mellitus is a group of diseases accumulating together, which will then affect how the body uses blood sugar (glucose). Glucose is the body’s energy mechanism to feed the cells and give strength to muscles and tissues. Glucose comes from the things you eat, mostly from the foods or drinks that include large amounts of sugar. “Diabetes is one of the most common diseases in the US. It is estimated that 16.7 million US adults (about 7% of the total adult US population) have diagnosed diabetes. About 1 million new cases of diabetes are diagnosed annually.” (Pittas, 2008) The main organ that is affected is the pancreas. With this disease, the levels of glucose are too low or too high, then insulin can be produced in the body. Insulin regulates

Reactive hypoglycemia, a rare form of hypoglycemia, increases insulin levels after the consumption of excess carbohydrates, leading to a drop in blood glucose levels. This differs from conventional hypoglycemia where blood glucose drops several hours after a meal, but can easily be returned to normal by the consumption of food. Reactive hypoglycemia can cause fatigue, dizziness, shakiness, and in extreme cases, a coma. Although no effective treatments exist, glucagon, a peptide hormone derived from pancreatic alpha cells, seems to reduce symptoms. In the proposed experiment, the effectiveness of glucagon relative to a regimen of dietary control, exercise, and Acarbose will be tested on Zucker-diabetic-fatty (ZDF) rats (Rattus rattus). Three

Diabetes mellitus, commonly known as diabetes, is a metabolic disorder characterized by chronic high blood sugar levels. It is caused by an absolute or functional deficiency of circulating insulin, resulting in an inability to transfer glucose from the bloodstream into tissues where it is needed as fuel (Ahmed, Laing and Yates 2011). The disruption in the metabolism of carbohydrates, fats and proteins interferes with the secretion or action of insulin, which plays a vital role in the metabolism and utilization of energy from the nutrients especially carbohydrates. Insulin is produced in the pancreas and secreted in the gastrointestinal tract in the response to high blood sugar levels after ingestion of a substance (REFERENCE).

Normally the level of glucose in the body rises after a person eats a meal. This rise in blood glucose stimulates the beta cells to release insulin. Insulin then either helps body cells take up glucose to use as energy or promotes the conversation of glucose to fat, which are used by the cells later. Some glucose maybe stored in the liver this is called glycogen. Then the level of glucose drops (usually several hours after the meal has been eaten), other cells in the pancreas stimulate the conversion of glycogen to glucose and its release into the bloodstream. In this way, the level of glucose in the bloodstream stays relatively constant until the next meal is eaten.

Glucose in your body comes from three major nutrients: fat, protein, and carbohydrate. About, 10 percent of the fat and 50 percent of the protein you eat eventually brakes down into it and 100 percent of the carbohydrates you eat. When a person who does not have diabetes eats any food, their blood glucose level rises; the beta cells detect this rise and release more insulin. The insulin goes into the liver telling it to make less glucose and to the muscles, fat cells to take up more.
