Biomacromaolecules are collected in

Options

A. Acid insoluble pool
B. Acid soluble pool
C. Ash analysis
D. Both 1 and 2

Answer

To answer the question regarding where biomacromolecules are collected, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Biomacromolecules**:
- Biomacromolecules are large, complex molecules that include proteins, nucleic acids, carbohydrates, and lipids. They are essential for various biological functions.

2. **Isolation of Biomacromolecules**:
- To isolate biomacromolecules from living tissues, a common method involves grinding the tissue and adding an acid. This process helps to separate the components based on their solubility.

3. **Separation into Layers**:
- After grinding the tissue and adding acid, two layers are formed:
- **Insoluble Acid Pool**: This layer contains larger, heavier molecular weight substances (macromolecules).
- **Soluble Acid Pool**: This layer contains smaller molecular weight components (micromolecules).

4. **Identifying the Correct Pool**:
- The question asks where biomacromolecules are collected. Since biomacromolecules are larger and heavier, they will be found in the **Insoluble Acid Pool**.

5. **Ash Analysis**:
- The mention of ash analysis refers to burning the tissue to analyze inorganic substances left after combustion. This process does not pertain to the collection of biomacromolecules, as it focuses on inorganic residues.

6. **Conclusion**:
- Based on the separation process, biomacromolecules are collected in the **Insoluble Acid Pool**.

### Final Answer:
Biomacromolecules are collected in the **Insoluble Acid Pool**.
