- Out of the given options, the processes or steps that are included as parts of the respiration in humans include alveolar diffusion of O2 and CO2, transport of gases by blood, and diffusion of O2 and CO2 between blood and tissues among others.
- However, the utilization of CO2 by cells for catabolic reactions is not considered a part of respiration in humans.
So, the correct answer is 'The utilisation of CO2 by cells for catabolic reactions'.

Respiration in Humans
Respiration is the process by which organisms exchange gases with the environment. In humans, respiration involves the following steps:
1. Pulmonary ventilation: The process of breathing in and breathing out air is called pulmonary ventilation. During inhalation, air enters the lungs and during exhalation, air leaves the lungs.
2. Alveolar gas exchange: The exchange of gases between the air in the alveoli and the blood in the pulmonary capillaries is called alveolar gas exchange. Oxygen (O2) from the air diffuses into the blood and carbon dioxide (CO2) from the blood diffuses into the air.
3. Transport of gases by blood: Oxygen is transported from the lungs to the body tissues by the red blood cells. Carbon dioxide is transported from the body tissues to the lungs by the red blood cells.
4. Systemic gas exchange: The exchange of gases between the blood and the body tissues is called systemic gas exchange. Oxygen diffuses from the blood into the body tissues and carbon dioxide diffuses from the body tissues into the blood.
5. Cellular respiration: The process by which cells utilize oxygen and nutrients to produce energy and release carbon dioxide is called cellular respiration.
Option 'A' - Utilisation of CO2 by cells for catabolic reactions is not a step in respiration. It is a step in cellular respiration, which is a metabolic process that occurs within the cells of an organism. Cellular respiration involves the breakdown of glucose and other nutrients to produce energy in the form of ATP. During this process, oxygen is consumed and carbon dioxide is produced. The carbon dioxide produced during cellular respiration is transported to the lungs for elimination during respiration.
