Respiratory quotient may be represented as

Options

A. `O_(2)` taken in `//CO_(2)` evolved
B. `CO_(2)` evolved `//O_(2)` taken in
C. `O_(2)` taken in
D. `CO_(2)` taken in

Answer

b

Explanation

During aerobic respiration `O_(2)` is consumed and `CO_(2)` is released. The ratio of the volume of `CO_(2)` evolved to the volume of `O_(2)` consumed in respiration over a period of time is called as respiratory quotient `(RQ)` or respiratory ratio.
`RQ = ("Volume of"CO_(2) "evolved")/("Volume of" O_(2) "consumed")`
