Glycogen is a homopolymer made up of

Options

A. Glucose units
B. Galactose unit
C. Ribose units
D. Amino untis

Answer

To solve the question "Glycogen is a homopolymer made up of", we will follow these steps:

### Step 1: Understand the Definition of Homopolymer
A homopolymer is a type of polymer that consists of only one type of monomer. In this case, we need to identify what the monomer of glycogen is.

**Hint:** Recall that polymers are large molecules made up of repeating units called monomers.

### Step 2: Identify the Monomer of Glycogen
Glycogen is specifically known to be a polymer made up of glucose units. Therefore, the monomer for glycogen is glucose.

**Hint:** Think about common polysaccharides and their building blocks. What is the basic unit of starch, cellulose, and glycogen?

### Step 3: Describe the Structure of Glycogen
Glycogen is structurally similar to amylopectin, another polysaccharide. It is composed of glucose units linked together primarily by α(1→4) glycosidic bonds, with branching occurring through α(1→6) linkages.

**Hint:** Consider how the structure of glycogen allows for energy storage. What kind of linkages are involved?

### Step 4: Explain the Function of Glycogen
Glycogen serves as a stored form of energy in animals, particularly in the liver and muscles. When energy is needed, glycogen can be broken down into glucose through a process called glycogenolysis.

**Hint:** Think about where glycogen is stored in the body and how it is utilized during physical activity.

### Step 5: Conclusion
Based on the information gathered, we can conclude that glycogen is a homopolymer made up of glucose units.

**Final Answer:** Glycogen is a homopolymer made up of glucose units.
