Solution

The correct option is D Utilisation of $C O_{2}$ by cells for catabolic reactions
Out of the given options, the processes or steps that are included as parts of the respiration in humans include alveolar diffusion of O $_{2}$ and CO $_{2}$ , transport of gases by blood, and diffusion of O $_{2}$ and CO $_{2}$ between blood and tissues among others. However, the utilization of CO $_{2}$ by cells for catabolic reactions is not considered a part of respiration in humans.

So, the correct answer is 'The utilisation of CO $_{2}$ by cells for catabolic reactions'.
