Production of Blood Sugar. In the case of blood sugar, a hormone stimulates the liver as well as the kidneys. The sugar that fuels many of the body's processes exists as glucose. The liver stores excess glucose and also synthesizes new glucose if the body's supply is low.Researchers have determined that the kidneys can synthesize glucose as well. The kidneys and the liver are stimulated to do this by low levels of the hormone insulin.roduction of Blood Sugar. In the case of blood sugar, a hormone stimulates the liver as well as the kidneys.

Carbohydrates, fats and proteins are referred to as the three energy-yielding nutrients because they provide your body with energy that is measured in calories. You'll also learn about another substance that can provide your body with calories, even though it is not a nutrient.
How Your Body Turns Carbohydrates into Energy A diet that provides sufficient amounts of carbohydrates keeps your body from eating its own muscles. Carbohydrates are an essential part of a healthy diet because your body converts them to glucose and your body runs on glucose. Proteins, fats, and alcohol (as in beer, wine, and spirits) also provide energy in the form of calories. And protein does give you glucose, but it takes a long time, relatively speaking, for your body to get it. 1  When you eat carbohydrates, your pancreas secretes insulin, the hormone that enables you to digest starches and sugars. This release of insulin is sometimes called an insulin spike.
