Collagen is an example of a(an)

Options

A. Enzyme
B. Structural protein
C. Storage protein
D. Transport protein

Answer

To determine what type of biomolecule collagen is, we can analyze the options provided: Enzyme, Structural Protein, Storage Protein, or Transport Protein.

### Step-by-Step Solution:

1. **Understanding Collagen**:
- Collagen is a type of protein found in various tissues throughout the body. It is known for its fibrous structure and is a major component of connective tissues.

2. **Analyzing the Options**:
- **Enzyme**: Enzymes are proteins that act as catalysts in biochemical reactions. They speed up reactions but do not provide structural support.
- **Structural Protein**: These proteins provide support and shape to cells and tissues. They are essential for maintaining the integrity of various structures in the body.
- **Storage Protein**: These proteins serve to store amino acids or other substances for later use. They do not primarily provide structure.
- **Transport Protein**: These proteins are responsible for transporting substances throughout the organism, such as hemoglobin transporting oxygen in the blood.

3. **Identifying the Correct Category for Collagen**:
- Given that collagen is primarily found in connective tissues such as skin, tendons, cartilage, bones, and ligaments, its main role is to provide structural support to these tissues.

4. **Conclusion**:
- Based on the analysis, collagen is best classified as a **Structural Protein**. Therefore, the correct answer is that collagen is an example of a structural protein.

### Final Answer:
Collagen is an example of a **Structural Protein**.
