pancreas
Your body seeks to convert glucose to glycogen and glycogen to glucose based on hormonal signals that are secreted in response to an event. i.e. if you ate tons of sugary food, your body will secrete a hormone called insulin from the beta cells of the pancreas, so that glucose in the blood will be able to be stored as glycogen in the muscle cells.
The body releases hormones to maintain the blood-sugar concentration. Insulin encourages the muscle and liver to absorb an insoluble form of glucose (glycogen) if the concentration rises too much. If the level falls, a second hormone - glucagon - is secreted to revert glycogen back into glucose, and stimulates the blood to absorb it. This homeostatic balance is crucial to our survival, as too little and too much sugar in the blood can be dangerous.
Any type of food does not contain glycogen. Starch and carbohydrate will become glucose after entering our body. The glucose is then converted into glycogen by insulin. For what purpose? To maintain the blood sugar level. If the blood sugar level decreases, glucagon will convert the glycogen into glucose again.
urea
No sypathetic nervous system does not raise blood sugar. It decreaces blood sugar concentration by providing that sugar(glucose) as an energy source to muscles which are under fight or flight response.

Glucose
liver glycogen
As blood glucose. But it is stored as glycogen in the liver.
The function of glycogen degradation is to export glucose to other tissues when blood glucose levels are low.
The other way around. When blood glucose levels are low, the liver converts stored sugar, glycogen, into blood sugar, glucose. You can remember it this way: glyco-GEN GEN-nerates glucose.
When blood glucose levels drop, it is vital for the body to help stabilize them prevent fainting. The body will take fat reserves and convert them to glucose to do this.

Diet & the liver (glycogen).
Glycogen is the type of carbohydrate which our body uses for storage. It is normally stored in muscles. It is important as a 'reserve' source of energy for our body. When the blood glucose level decreases, insulin converts glycogen into glucose so as to bring it to the normal blood glucose level.
The body releases hormones to maintain the blood-sugar concentration. Insulin encourages the muscle and liver to absorb an insoluble form of glucose (glycogen) if the concentration rises too much. If the level falls, a second hormone - glucagon - is secreted to revert glycogen back into glucose, and stimulates the blood to absorb it. This homeostatic balance is crucial to our survival, as too little and too much sugar in the blood can be dangerous.
The liver and skeletal muscle store glucose as glycogen. The liver can make glucose from proteins and release it from glycogen to help keep blood glucose at a normal level when we are fasting.
