The correct answer is: nature of the substrate
R Q is the ratio of the volume of $\mathrm{CO}_2$ eleased to the volume of oxygen taken in respiration. It depends on the nature of the substrate, which is oxidised, for carbohydrates $\mathrm{R} Q$ is one, for fats and protein less then one, and is more than one for organic acids.
