what makes insulin
Insulin is a hormone. It makes our body's cells absorb glucose from the blood. The glucose is stored in the liver and muscle as glycogen and stops the body from using fat as a source of energy.When there is very little insulin in the blood, or none at all, glucose is not taken up by most body cells.nsulin is also released when glucose is present in the blood. After eating carbohydrates, blood glucose levels rise. Insulin makes it possible for glucose to enter our body's cells-without glucose in our cells they would not be able to function.
