Q. The respiratory quotient (RQ) or respiratory ratio is
A) $RQ\ = \ \frac{Volume\ of\ O_{2}\ evolved}{Volume\ of\ CO_{2}\ consumed}$
B) $RQ\ = \frac{Volume\ of\ O_{2}\ consumed}{Volume\ of\ CO_{2}\ evolved}$
C) $RQ\ = \frac{Volume\ of\ CO_{2}\ consumed}{Volume\ of\ O_{2}\ evolved\ }$
D) $RQ\ = \frac{Volume\ of\ CO_{2}\ evolved}{Volume\ of\ O_{2}\ consumed}$
Explanation
RQ is the ratio of volume of carbon dioxide evolved and volume of oxygen consumed.
