How does insulin regulate blood sugar in your body?

Answer 1

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.

Answer 2

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.

Answer 3

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.

Answer 4

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:

1. Change the amount of glycogen be converted to glucose.
2. Increase the amount of glucose cells absorb.
3. Increase the catabolism of glucose.
4. 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.

Answer 5

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.

Answer 6

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)

Answer 7

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.

Answer 8

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.

Answer 9

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.

Answer 10

Insulin lowers the glucose level in your blood.
