What is the primary function of the liver and skeletal muscles in relation to glucose?

The primary function of the liver and skeletal muscles in relation to glucose is glucose storage. The liver plays a crucial role in maintaining blood glucose levels, particularly during fasting or after meals. It stores glucose in the form of glycogen, which can be rapidly converted back to glucose when needed, such as during periods of low blood sugar or increased physical activity.

Skeletal muscles also store glucose as glycogen, which serves as an energy reserve that can be utilized during exercise. When muscles are active, they can mobilize their stored glycogen to produce the energy required for muscle contraction. This cooperative function between the liver and skeletal muscles ensures a steady supply of glucose, which is vital for maintaining energy homeostasis within the body.

While protein synthesis, fat metabolism, and amino acid transport are important functions of the liver and skeletal muscles, they do not directly address the specific role of these organs in glucose management and storage, making glucose storage the most pertinent answer in this context.
