The glucose that is not stored in the liver is used to produce energy by a process called [[1]].

Glucose that is not stored as glycogen in the liver is used to produce energy via glycolysis. 

This metabolic pathway involves the breakdown of glucose into two pyruvate molecules, the release of energy in the form of ATP, and the reduction of the coenzyme NAD+ to NADH. 

This energy is used by the liver to perform various functions such as detoxification, hormone regulation, and glucose homeostasis. 

By breaking down glucose and producing energy, glycolysis helps to regulate glucose levels in the body and ensures that cells have a steady supply of energy.
