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.
