Floating respiration is respiration

Options

A. Occurring in cytosol
B. Using carbohydrate as substrate
C. Employing fat as respiratory substrate
D. Both B and C

Answer

**Step-by-Step Solution:**

1. **Understanding Floating Respiration**:
- Floating respiration refers to a type of respiration where different substrates are used for energy production. The primary substrates in respiration are carbohydrates (like glucose) and fats.

2. **Identifying the Substrates**:
- The most common substrate for respiration is glucose, which is a carbohydrate. Fats can also be used as substrates for respiration, especially when glucose levels are low.

3. **Analyzing the Options**:
- The question provides several options regarding floating respiration:
- A) Occurring in cytosol
- B) Using carbohydrate as substrate
- C) Employing fat as respiratory substrate
- D) Both B and C

4. **Evaluating Each Option**:
- **Option A**: "Occurring in cytosol" - This is incorrect because respiration occurs in both the cytosol (for glycolysis) and the mitochondria (for the Krebs cycle).
- **Option B**: "Using carbohydrate as substrate" - This is correct since carbohydrates like glucose are commonly used in respiration.
- **Option C**: "Employing fat as respiratory substrate" - This is also correct as fats can be utilized for energy production.
- **Option D**: "Both B and C" - Since both B and C are correct, this option is also correct.

5. **Conclusion**:
- The correct answer to the question is option D) Both B and C, as floating respiration can utilize both carbohydrates and fats as substrates.
