Respiratory Quotient is measured by

Options

A. anemometer
B. psychrometer
C. feffer's Respirometer
D. ganong's Respirometer

Answer

**Step-by-Step Solution:**

1. **Understanding 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.
- It is a measure that indicates the type of substrate being metabolized for energy.

2. **Formula for Respiratory Quotient:**
- The formula to calculate RQ is:
\[ RQ = \frac{\text{Volume of CO2 eliminated}}{\text{Volume of O2 consumed}} \]

3. **Importance of RQ:**
- RQ is a dimensionless number and is crucial for understanding metabolic processes and calculating the basal metabolic rate (BMR).

4. **Measuring Respiratory Quotient:**
- The measurement of RQ is typically done using a specific device known as a respirometer.
- The device used for this purpose is called Gannon's Respirometer.

5. **Conclusion:**
- Therefore, the Respiratory Quotient is measured using Gannon's Respirometer.

**Final Answer:**
The Respiratory Quotient is measured by Gannon's Respirometer.
