Is unused glucose converted into glycogen and stored in the liver?

Yes, unused glucose is converted into glycogen and stored in the liver through a process called glycogenesis. This storage form of glucose can be quickly mobilized when the body needs energy, such as between meals or during physical activity. The liver plays a crucial role in maintaining blood glucose levels by releasing glycogen as needed. However, if glycogen stores are full, excess glucose can be converted into fat for long-term storage.
