When we homogenise any tissue in an acid the acid soluble pool represents

Options

A. cytoplasm
B. cell membrane
C. nucleus
D. mitochondria

Answer

To solve the question "When we homogenise any tissue in an acid, the acid soluble pool represents:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Homogenization**:
- Homogenization is a process where biological tissues are broken down into smaller components, allowing for the extraction of various cellular fractions. This process often involves using a buffer or acid to facilitate the breakdown of cellular structures.

**Hint**: Think about what homogenization does to the cellular structure and what components are released.

2. **Identifying the Acid-Soluble Pool**:
- When tissues are homogenized in an acid, the soluble components that are released into the solution are referred to as the acid-soluble pool. This pool contains various biomolecules that can dissolve in acidic conditions.

**Hint**: Consider the types of biomolecules that are typically soluble in acid.

3. **Comparing Cellular Components**:
- The main cellular components include the cytoplasm, cell membrane, nucleus, and mitochondria. We need to determine which of these components would primarily consist of the acid-soluble pool.
- The cytoplasm contains a wide variety of biomolecules, including proteins, nucleotides, and small metabolites, which are generally soluble in acid.

**Hint**: Recall the composition of the cytoplasm and how it differs from other cellular components.

4. **Evaluating Other Options**:
- The cell membrane is primarily composed of lipids, which are not soluble in acid.
- The nucleus contains DNA and other macromolecules that are also not soluble in acid.
- Mitochondria, while containing enzymes and other proteins, are not represented in the acid-soluble pool as they are more complex structures.

**Hint**: Think about the solubility of different biomolecules in acid and which cellular structures are made up of these biomolecules.

5. **Conclusion**:
- Based on the analysis, the acid-soluble pool primarily represents the cytoplasm because it contains a variety of soluble biomolecules that can be extracted during the homogenization process.

### Final Answer:
The acid soluble pool represents the **cytoplasm**.
