● During `color{violet}"aerobic respiration"`, `O_2` is `color{violet}"consumed"` and `CO_2` is `color{violet}"released"`.
● The `color{violet}"ratio of the volume"` of `CO_2` evolved to the volume of `O_2` consumed in `color{violet}"respiration"` is called the `color{Brown}"respiratory quotient"` `color{violet}"(RQ)"` or `color{Brown}"respiratory ratio"`.
● The `color{violet}"respiratory quotient"` depends upon the type of `color{violet}"respiratory substrate"` used during `color{violet}"respiration"`.
● When `color{violet}"carbohydrates are used as substrate"` and are `color{violet}"completely oxidised"`, the `color{Brown}"RQ will be 1"`, because `color{violet}"equal amounts"` of `CO_2` and `_O`2 are evolved and consumed, respectively, as shown in the `color{violet}"equation below"` :
.
● When `color{violet}"fats are used"` in respiration, the `color{Brown}"RQ is less than 1"`.
● Calculations for a `color{violet}"fatty acid, tripalmitin"`, if used as a substrate is shown:
● When `color{violet}"proteins are respiratory substrate"`s the ratio would be about `color{Brown"0.9"`.
● What is important to recognise is that in `color{violet}"living organisms respiratory substances"` are often more than one; `color{violet}"pure proteins or fats"` are never used as `color{violet}"respiratory substrates"`.
