Question

Quizplus · Accepted Answer

The carbohydrate reservoir in the liver, in the form of glycogen, is primarily reserved for use by the central nervous system, which relies heavily on glucose as a fuel source. With the help of enzymes, the liver can break down glycogen into glucose and release it into the bloodstream to maintain normal blood glucose levels and fuel the brain. While muscles can also use stored glycogen as an energy source during exercise, the liver primarily serves the needs of the central nervous system.
