insulin and glucagon are examples of what type of substance
The alpha cells of the pancreas are the source of release glucagon.
Insulin is a hormone released by the beta cells in your pancreas, when there is glucose (sugar) in your blood. Insulin goes through the blood stream and basically tells the cells of the body that there is glucose in the blood stream. and the cells respond to it by stopping glucagon breakdown, start making glucagon, taking up glucose into the cells with glucose transporters. A hormone is a molecule that is released in one part of the body, but works in another.

(1) alpha cells: glucagon; (2) beta cells: insulin; (3) delta cells: growth hormone-inhibiting hormone (GH-IH, or somatostatin); and (4) F cells: pancreatic polypeptide

Glucagon and Insulin
Insulin reduces the amount of sugar in your bloodstream to an acceptable level, and glucagon raises the amount of sugar in your bloodstream to an acceptable level. Glycogen is a stored type of the sugar, Glucose, that can readily be added to the bloodstream by glucagon.
Glucagon, yes. Cortisol, probably not. Glucagon raises blood sugar. Many type one diabetics own glucagon injectors, so that when their blood sugar goes too low they (or someone with them) can inject them with glucagon. Cortisol does raise blood sugar, but it is not used to raise blood sugar. It's used to treat many other diseases, but not the low blood sugar which type 1 diabetics sometimes get.
First, understand that a hormone is a type of enzyme. Insulin and glucagon are the two hormones in the pancreas. If you have too much glucose in your blood (i.e. eating a lot of carbohydrates like pasta, bread, fruits, milk, cake, and so on) then the hormone insulin will come out. Insulin decreases blood glucose. If you have to little glucose in your blood (i.e. exercising for a while without eating carbohydrates, not eating for days, etc.) then the hormone glucagon will come out. Glucagon increases the supply of glucose in your blood.

Insulin is a hormone that regulates carbohydrate and fat metabolism in the body. Insulin causes cells in the liver, muscle, and fat tissue to take up glucose from the blood, storing it as glycogen in the liver and muscle.
Sulfonylurea drugs work by increasing insulin secretions. Examples include Glucotrol, Amaryl, glipizide and many others.
The pancreas is supposed to make insulin, glucagon, and enzymes. When you become a diabetic, either the pancreas stops making insulin, or the cells in the body are unable to use insulin. If the pancreas stops making insulin, that is type one diabetes, and if the body cannot use insulin, that is type two diabetes. While it is possible to cause type one diabetes with alcohol abuse, both forms of diabetes are often a result of an immune response. Type one diabetes is usually childhood onset, and a virus or the immune system attacks the pancreas. Type two diabetes is often acquired through bad diet. You might get so much fat and plaques from the fat that the body mistakes it for invaders. So the body ends up targeting insulin receptors.
No. Type 1 diabetes is known as insulin-dependent or juvenile onset diabetes. The causes of type 2 diabetes can either be a lack of insulin sensitivity or insulin production problem. Some people with type 2 diabetes take insulin, but it is not known as insulin-dependent diabetes.
Insulin resistance is caused by obesity and a family history of insulin resistance. You can develop insulin resistance without these, but it's rare. Insulin resistance leads to type 2 diabetes. A type 1 diabetic can develop insulin resistance the same way anyone else does, but becoming obese and by having insulin resistance in the family. In this case, the insulin resistance and the type 1 diabetes are totally unrelated.
