Question

a liver cell synthesizes glycogen from glucose. metabolism for energy energy storage protein synthesis structural support

Explanation:

When a liver cell synthesizes glycogen from glucose, it is storing energy. Glycogen is a polysaccharide that serves as an energy - storage molecule in animals. When the body needs energy, glycogen can be broken down back into glucose. It has nothing to do with protein synthesis (which involves amino acids) or structural support (which is mainly the function of structural proteins like collagen). While glucose can be metabolized for energy directly, the synthesis of glycogen is about storing energy for later use.

Answer:

energy storage
