Glycogen is a homopolymer made of ................units.

Explanation

To answer the question "Glycogen is a homopolymer made of ................units," we can follow these steps:

1. **Understanding Glycogen**: Glycogen is a type of polysaccharide that serves as a form of energy storage in animals and fungi. It is primarily found in the liver and muscle tissues.

2. **Identifying the Monomer**: The basic building block or monomer of glycogen is glucose. Specifically, glycogen is composed of multiple glucose units linked together.

3. **Structure of Glycogen**: Glycogen is classified as a homopolymer because it is made up of only one type of monomer, which is glucose. It is a branched polymer, meaning that it has a complex structure with both linear and branched chains.
