Respiration of starved leaves (consuming proteins) is called

Options

A. protoplasmic respiration
B. floating respiration
C. photorespiration
D. oxidative phosphorylation

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the type of respiration that occurs in starved leaves when they consume proteins.

2. **Identifying the Options**: The options provided are:
- Option 1: Protoplasmic respiration
- Option 2: Floating respiration
- Option 3: Photorespiration
- Option 4: Oxidative phosphorylation

3. **Analyzing Protoplasmic Respiration**: Protoplasmic respiration occurs when cells utilize proteins as a respiratory substrate, especially during starvation. In this process, proteins are broken down to provide energy.

4. **Evaluating Other Options**:
- **Floating Respiration**: This type of respiration involves the use of carbohydrates, proteins, and fats from outside the body. It does not specifically refer to the internal consumption of proteins during starvation, making it an incorrect choice.
- **Photorespiration**: This process occurs in C2 plants and is related to the fixation of oxygen and carbon dioxide, not specifically linked to protein consumption in starved leaves. Therefore, it is also incorrect.
- **Oxidative Phosphorylation**: This process involves the formation of ATP in the presence of oxygen and does not specifically refer to the breakdown of proteins in starved leaves. Thus, it is not the correct answer.

5. **Conclusion**: Given that protoplasmic respiration is the only option that directly relates to the consumption of proteins in starved leaves, it is the correct answer.

**Final Answer**: The respiration of starved leaves consuming proteins is called **Protoplasmic respiration**.
