what does the Liver do when stimulated by Glucagon?

Question

i know it will function to increase the blood glucose level, e.g. it stimulates the breakdown of stored glygogen.
what else?

what else does it do to bring the glucose level to normal?

Answer 1

Glucagon

Class: Hormone (antihypoglycemic agent).
Actions: Causes breakdown of glycogen to glucose.
Inhibits glycogen synthesis.
Elevates blood glucose level.
Increases cardiac contractile force.
Increases heart rate.
Indications: Hypoglycemia.
Contraindications: Hypersensitivity to the drug.
Precautions: Only effective if there are sufficient stores of Glycogen within the liver. Use with caution in patients with cardiovascular or renal disease. Draw blood glucose before administration.


So in the presence of glucagon, the liver breaks down the stored glycogen into glucose. Glucose is the sugar our bodies use for both physical and mental energy. When our bodies sense an increase of glucose in the blood, it immediately directs the pancreas to push insulin into the blood stream. With the insulin, the body is able to burn the glucose as energy. If there's too much glucose in the blood stream to be used as energy, the glucose can be changed to glycogen, the body's short-term storage energy supply. And if the glycogen pool is already full, the body will turn it into long term storage in the form of fat. Different blood-sugar effects possible after
eating a high concentration of sucrose sugar.
.
Eating a huge amount of sugar at once with it's resultant spike in the blood-sugar level can cause stress to a weak pancreas as it struggles to deliver enough insulin to bring down the blood-sugar to acceptable levels.


This cycle is especially hard on people who have an abnormal pancreas. If the pancreas doesn't produce enough insulin that person is considered diabetic. If it produces too much insulin they are considered hypoglycemic. These people will generally suffer from an abnormal glucose level depending on what their condition is.


If things are working normally, the pancreas produces just enough insulin to bring the blood-sugar level back down to normal. If they are diabetic and no medication is given, there isn't enough insulin produced and the blood-sugar level remains elevated. In a hypoglycemic person, as the blood-sugar level raises, their over-active pancreas dumps too much insulin into the blood stream and they end up with low blood sugar levels which creates it's own have.


Using fructose instead of sucrose puts a strong damper on many of these problems. Your body can't use fructose without converting it into glucose in the liver. Actually, most of the time, however, unless your body needs to immediately increase it's blood-sugar level, the liver changes fructose into glycogen first. We have already mentioned glycogen which is the body's short term energy supply. A typical adult will have as much as 3/4 pound of glycogen in their various tissues at one time, mostly stored in the liver and muscles. As the glucose level in the blood begins to drop, the liver can rapidly convert this stored glycogen

Answer 3

When you eat, your pancreas releases insulin, which stimulates the cell to release vesicles containing glucose transporters, this way, glucose is able to easily diffuse across the cell membrane. After you finish eating and enter a fasting state, your pancreas releases glucagon, which is later broken down to glucose and the same process of diffusion across the cell occurs. Your body stores most of the carbohydrates as glycogen, in the liver. This is broken down or used when Carb. reserves are low in the body.

Answer 4

Glucagon causes the liver to release glucose into the bloodstream. When the stored glucose is depleted, glucagon encourages to the liver to synth more from stored glycogen.

Basically it causes blood sugar levels to increase and prevent hypoglycemia.

Lovely, I got thumbsed-down because I copied from an encyclopaedia?

Answer 5

What Does Glucagon Do

Answer 6

glucagon sounds like a diabetes med, and that works with the pancreas not the liver

Answer 7

As well as releasing glucose from the body to the bloodstream it also increases release of urea and fatty acids. I cant see what else you want as that's the basic function of the drug. It is used in a diabetic in a hypo to rapidly raise their blood glucose levels;
