When respiratory substrate is fat, respiration Is called

Options

A. protoplasmic respiration
B. floating respiration
C. cellular respiration
D. dark respiration

Answer

To answer the question "When respiratory substrate is fat, respiration is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Respiration**:
- There are various types of respiration based on the substrates used. The common substrates include carbohydrates, fats, and proteins.

2. **Identify the Options**:
- The options provided are:
- A) Protoplasmic respiration
- B) Floating respiration
- C) Cellular respiration
- D) Dark respiration

3. **Analyze Each Option**:
- **Protoplasmic Respiration**: This occurs when carbohydrates and fats are exhausted, and proteins become the substrate. This is not applicable here since we are specifically looking for respiration using fats.
- **Floating Respiration**: This type of respiration can utilize both carbohydrates and fats as substrates. Since the question specifies that the substrate is fat, this option is relevant.
- **Cellular Respiration**: This is a broad term that encompasses all types of respiration occurring in cells, regardless of the substrate. It does not specifically refer to respiration with fats.
- **Dark Respiration**: This involves the enzymatic combination of organic molecules (like glucose) with oxygen to release energy and carbon dioxide. It is not specifically related to the use of fats as a substrate.

4. **Determine the Correct Answer**:
- Given the analysis, the correct answer is **Floating Respiration**. This is because when the respiratory substrate is fat, the respiration process is referred to as floating respiration.

### Final Answer:
When the respiratory substrate is fat, respiration is called **Floating Respiration**.
