Microspheres possessed a membrane of

Options

A. Lipid and protein
B. Lipid
C. Cabohydrates
D. Fats

Answer

**Step-by-Step Solution:**

1. **Understanding Microspheres**: Microspheres are tiny spherical structures that are formed from the aggregation of certain organic molecules. They are often studied in the context of the origin of life.

2. **Role of Sidney Walter Fox**: Sidney Walter Fox was a biochemist known for his research on the origin of life. He discovered that amino acids could be synthesized from inorganic molecules, leading to the formation of proteins.

3. **Definition of Proteinoids**: Fox introduced the term "proteinoids" to describe the polymers of amino acids he synthesized. These proteinoids are crucial in the formation of early life structures.

4. **Formation of Microspheres**: The first protocells, which are primitive cell-like structures, are formed from proteinoids and water. These structures are referred to as microspheres.

5. **Composition of Microspheres**: The question asks about the membrane composition of microspheres. Based on scientific findings, microspheres are known to possess a membrane primarily made of lipids.

6. **Conclusion**: Therefore, the correct answer to the question "Microspheres possessed a membrane of" is **lipid**.
