Arrange these respiratory substrates used in aerobic respiration in increase order of their respiratory quotients.

Options

A. Protein - Triplamitin - Oxalic acid - Glucose
B. Protein - Triplamitin - Glucose -Oxalic acid
C. Triplamitin -Protein -Oxalic acid - Glucose
D. Triplamitin -Protein -Glucose- Oxalic acid

Answer

To solve the question of arranging respiratory substrates in increasing order of their respiratory quotients (RQ), we need to first understand what RQ is and then identify the RQ values for each substrate given.

### Step-by-Step Solution:

1. **Understand Respiratory Quotient (RQ)**:
- The respiratory quotient is defined as the ratio of the volume of carbon dioxide (CO2) produced to the volume of oxygen (O2) consumed during respiration.
- RQ = CO2 produced / O2 consumed

2. **Identify the RQ values of the given substrates**:
- **Tripalmitin**: RQ = 0.7
- **Proteins**: RQ = 0.8
- **Glucose**: RQ = 1.0
- **Oxalic Acid**: RQ = 4.0

3. **List the RQ values**:
- Tripalmitin: 0.7
- Proteins: 0.8
- Glucose: 1.0
- Oxalic Acid: 4.0

4. **Arrange the substrates in increasing order of RQ**:
- Start with the lowest RQ value:
- 1st: Tripalmitin (0.7)
- 2nd: Proteins (0.8)
- 3rd: Glucose (1.0)
- 4th: Oxalic Acid (4.0)

5. **Final Arrangement**:
- Increasing order of respiratory quotients:
- Tripalmitin < Proteins < Glucose < Oxalic Acid

### Final Answer:
**Tripalmitin < Proteins < Glucose < Oxalic Acid**
