Serum albumin is an example of a(an)

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding Serum Albumin**: Serum albumin is a protein found in blood plasma. It plays a crucial role in maintaining osmotic pressure and transporting various substances in the bloodstream.

2. **Identifying Protein Types**: Proteins can be classified into several categories based on their functions:
- **Enzymes**: Biocatalysts that speed up chemical reactions.
- **Structural Proteins**: Provide support and structure to cells and tissues.
- **Storage Proteins**: Store amino acids or other substances for later use.
- **Transport Proteins**: Carry substances throughout the body.

3. **Analyzing the Function of Serum Albumin**: Serum albumin binds to various molecules, including hormones and fatty acids, and facilitates their transport in the bloodstream. This indicates that its primary function is to transport substances.

4. **Conclusion**: Given that serum albumin binds and transports molecules in the blood, it is classified as a transport protein.

5. **Final Answer**: Serum albumin is an example of a transport protein.
