Question
Which of the following is the apparatus to measure rate of respiration and RQ?
- Auxanometer
- Potometer
- Respirometer
- Manometer
Hint:
The respiratory quotient (RQ) or respiratory ratio is defined as the volume of carbon dioxide released by a tissue to the volume of oxygen absorbed during the process of cellular respiration.
The correct answer is: Respirometer
A respirometer is a device or apparatus used to measure the respiratory ratio i.e. the rate of preparation of a living organism by measuring its rate of exchange of oxygen and/or carbon dioxide.
