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.
When you eat too many calories, especially in the form of sugars and quickly burned starches, your body may reach its storage capacity for glycogen. The liver converts the stored sugars into triglycerides, or fats, so that the excess energy can be transported to the fat cells for longer-term storage. Your fat cells release this energy when needed. If you eat more calories than you burn, your body will continue to store the fat. Recommendations Carbohydrates form the base of the U.S. Department of Agricultureâs Food Pyramid, and nutrition experts recommend that most people get between 45 and 65 percent of their calories from carbohydrate-rich foods.
