What are substrates of floating and protoplasmic respiration respectively

Options

A. Fat and carbohydrate
B. Protein and carbohydrate
C. Carbohydrate and protein
D. Fat and lipid

Answer

To answer the question regarding the substrates of floating and protoplasmic respiration, we can follow these steps:

### Step 1: Understand the Types of Respiration
- **Floating Respiration**: This is a common type of respiration that primarily utilizes carbohydrates and fats as substrates.
- **Protoplasmic Respiration**: This is a rarer form of respiration that uses proteins as its substrate, typically occurring when carbohydrates and fats are depleted.

### Step 2: Identify the Substrates
- For **Floating Respiration**, the substrates are **Carbohydrates and Fats**.
- For **Protoplasmic Respiration**, the substrate is **Proteins**.

### Step 3: Match the Substrates to the Options
- The question provides several options:
1. Fats and Carbohydrates
2. Protein and Carbohydrate
3. Carbohydrate and Protein
4. Fats and Lipid

From our understanding:
- Floating Respiration uses **Carbohydrates**.
- Protoplasmic Respiration uses **Proteins**.

### Step 4: Choose the Correct Option
- The correct option that matches our findings is **Carbohydrate and Protein** (Option 3).

### Final Answer
The substrates of floating and protoplasmic respiration respectively are **Carbohydrates** and **Proteins**.
