Insulin is released by the pancreas, and serves two important functions in blood-glucose control. Firstly, it encourages muscle and liver cells to take glucose from the blood. This is all very well, but glucose is soluble in the cytoplasm, and this poses a problem for osmoregulation, in the cells, so insulin also stimulates the conversion of glucose into glycogen - an insoluble sugar, which can then be stored until it is needed for respiration by cells.
Insulin is a hormone produced by the pancreas that helps regulate blood sugar by facilitating the uptake of glucose from the blood into cells. It promotes the storage of excess glucose in the liver and muscles as glycogen. Insulin also inhibits the production of glucose by the liver.
Insulin and glucagon are two hormones that are released by the pancreas to regulate the blood glucose levels. Insulin is secreted when you have just eaten. It serves two main functions: to encourage the muscle and liver cells to absorb glucose from the blood, and also to convert glucose to glycogen, so as not to affect osmo-regulation in the cells. Whenever your body needs more glucose to convert into energy, glucagon is released to both convert glycogen back into glucose, and stimulates the transfer from muscles/liver into the blood vessels.
Good question!
In short, the pancreas monitors your blood glucose level via its beta cells. Under the circumstance that you exceed 90ml/dl, the pancreas secretes insulin. This insulin is absorbed into the blood stream and it binds to the beta globulins in your blood in order to promote circulation. As the insulin makes contact with the cells of your muscles and liver, it starts its work. It can perform any of the following:
- Change the amount of glycogen be converted to glucose.
- Increase the amount of glucose cells absorb.
- Increase the catabolism of glucose.
- Increase the production of fat.
I hope this helped!

In addition:
A system that can only decrease glucose level is only half complete. The pancreas also makes another type of hormone called glucagon. Glucagon is produced in the alpha cells of the pancreas islets and is released when the blood glucose level is too low. Glucagon works almost exactly in reverse to insulin, and promotes an increase in blood glucose levels.
Insulin has the opposite effect of Adrenaline.
Adrenaline alerts Our Bodies to respond to a 'fight or flight' situation.
The role of Insulin is the Opposite; it's role is to signal 'that it is Time to deposit' sugars back into Storage.
Insulin response comes about from receptor tyrosine kinase. When insulin binds to the alpha portion of the RTK, the receptors dimerize. This results to its beta intracellular portion to autophosphorylate. This creates a binding site for IRS-1. When IRS-1 is activated, it recruits glut-4 receptors, allowing glucose to be taken in from the blood (therefore blood conc. will fall under insulin)
Insulin will make the liver remove the glucose as soon as it enters the blood from the gut, when the food is being digested. This stops the level of glucose in the blood from getting too high.
Insulin performs multiple tasks-
1) It forces glucose into the body's cells, diminishing the glucose in the blood
stream;
2) It changes carbohydrates into fat and fat into carbohydrates, depending on
the body's needs;
3) It aids the liver in metabolizing carbohydrates.
Glucagon is a hormone that is produced by the pancreas when the blood sugars are low. This will inform the Liver to dump stored sugar into the blood stream to try and increase the low level of sugar in the body.
Blood sugar levels must its transport across cell membranes must be regulated. That job is made by the protein hormone insulin. Insulin is secreted by the islets of Langerhans in the pancreas and also has anabolic effects on protein and lipid metabolism. The main effect od insulin is lowering the levels of blood sugar and stimulating the utilization of glucose by affecting the rate of transport of glucose across the cell membrane.
More in detail; basal state fat and muscle cells store most of their glucose transporters in internal membranous vesicles. Upon insulin stimulation, these vesicles fuse with the plasma membrane in a process known as exocytosis. The consequent increased number of cell-surface glucose transporters, or GLUT4, results in a proportional increase in the cell's glucose uptake rate. Upon insulin withdrawal, the process is reversed through the endocytosis of plasma membrane-embedded glucose transporters.

Name the protein that controls the amount of sugar in the blood?
Insulin is the protein that controls the amount of sugar in the blood. It is produced by the pancreas and helps regulate blood sugar levels by promoting the uptake of glucose from the blood into cells for energy.
What hormone does the panreas secret?
The pancreas secretes insulin and glucagon, which are hormones that help regulate blood sugar levels in the body. Insulin lowers blood sugar levels, while glucagon helps raise them when they are too low.
Which is the organ which produces insulin that keeps the sugar level balanced in the body?
The pancreas is the organ that produces insulin, a hormone that helps regulate blood sugar levels in the body by allowing cells to take in glucose from the bloodstream for energy.
What part of the brain controls your blood sugar levels?
The hypothalamus and the pancreas work together to regulate blood sugar levels in the body. The hypothalamus signals the pancreas to release insulin or glucagon based on the body's needs to maintain blood sugar balance.
What produces the hormones insulin and glucagon?
Insulin is produced by beta cells in the pancreas, while glucagon is produced by alpha cells in the pancreas. These hormones work together to regulate blood sugar levels in the body.
It is used to stimulates body cells to take up and use blood sugar?
This describes the action of insulin, a hormone produced by the pancreas. Insulin helps regulate blood sugar levels by triggering cells in the body to absorb glucose from the bloodstream for energy. This process is essential for maintaining proper blood sugar balance in the body.
Name the protein that controls the amount of sugar in the blood?
Insulin is the protein that controls the amount of sugar in the blood. It is produced by the pancreas and helps regulate blood sugar levels by promoting the uptake of glucose from the blood into cells for energy.
What hormone does the panreas secret?
The pancreas secretes insulin and glucagon, which are hormones that help regulate blood sugar levels in the body. Insulin lowers blood sugar levels, while glucagon helps raise them when they are too low.
What is the chemical substance released into the blood by the pancreas that enables the body to use sugar as a fuel in the process of respiration?
Insulin is the chemical substance released by the pancreas into the blood that enables the body to use sugar as a fuel in the process of respiration. Insulin helps regulate blood sugar levels by facilitating the uptake of glucose into cells for energy production.
Why should you regulate blood sugar?
Your body regulates blood sugar. It is only if you have too much sugar (and carbohydrates break down into sugar) that the body can not keep up, does it become a problem. When you eat large amounts of sugar or carbohydrates, it requires the body to continuously produce high levels of insulin to keep that sugar level down. (Insulin's job is to push sugar out of the bloodstream into the cells where it is used for energy.) Eventually the cells in their body becomes insensitive to the effects of the insulin (insulin resistance). To handle this problem of insulin resistance their body begins to produce even higher levels of insulin. This continues until their pancreas reaches the maximum amount of insulin it can produce, and when the insulin resistance increases again, their blood sugar begins to rise out of control. The result is type 2 diabetes! Type 2 diabetes is actually an extreme case of insulin resistance. It is then that you have to regulate your blood sugar via diet, excerise and give you body some help to make the body's cells sensitive again to the insulin.
What is the function of the pancreus?
To produce digestive enzymes to be used in the intestines and to produce insulin to regulate the body's use of blood sugar.
What is the difference between high blood sugar and diabetes?
A person can have a temporary high blood sugar that then goes back to normal. Diabetes is a condition in which the body cannot regulate insulin.
What does insuline do for the body?
It regulates the blood glucose so you do not get too much "sugar" in your blood with food intake. It is naturally produced by the pancreas and is released in response to rising blood sugar levels. In diabetics, there is no (or not enough) production of insulin by the body or other problems with the endocrine system affecting the efficacy of the insulin and that is why diabetics take medication, including insulin, to treat their disease and regulate the blood sugar.
Why does the body release insulin after a meal high in carbohydrates?
The body releases insulin after a high-carbohydrate meal to help regulate blood sugar levels. Insulin helps transport glucose from the bloodstream into the cells for energy production or storage. This process prevents blood sugar levels from rising too high, which can be harmful to the body.
Which is the organ which produces insulin that keeps the sugar level balanced in the body?
The pancreas is the organ that produces insulin, a hormone that helps regulate blood sugar levels in the body by allowing cells to take in glucose from the bloodstream for energy.
What organ releases insulin into the duodenum?
The pancreas releases insulin into the bloodstream, not directly into the duodenum. Insulin is released in response to high blood sugar levels to regulate glucose metabolism throughout the body.
The absence of insulin leads to the loss of?
The absence of insulin leads to the loss of glucose control in the body, resulting in high blood sugar levels. Over time, this can lead to complications such as diabetic ketoacidosis, nerve damage, and organ damage.
