The term protoplasmic respiration is used for the respiration of

Options

A. Organic acids
B. Fats
C. Carbohydrates
D. Proteins

Answer

**Step-by-Step Solution:**

1. **Understanding Protoplasmic Respiration**: Protoplasmic respiration refers to the type of respiration that occurs within the protoplasm of cells. It is essential for the metabolic processes that sustain life in plant cells.

2. **Identifying the Classification of Respiration**: The classification of respiration was proposed by the scientist Blackman, who categorized respiration based on the type of respiratory substrates used.

3. **Types of Respiration**: Blackman identified two types of respiration:
- **Floating Respiration**: This type of respiration primarily utilizes carbohydrates and fats as respiratory substrates.
- **Protoplasmic Respiration**: In contrast, this type of respiration utilizes proteins as the primary respiratory substrate.

4. **Conclusion**: Since protoplasmic respiration specifically involves the use of proteins, the correct answer to the question is that protoplasmic respiration is associated with the respiration of **proteins**.

**Final Answer**: The term protoplasmic respiration is used for the respiration of **proteins**.
