oxygen
Carbon dioxide is created during respiration.
The gas in the atmosphere important to respiration is oxygen. It is taken in by animals during breathing and used in cellular respiration to produce energy for their cells.
Oxygen
Oxygen is the gas used up in respiration. It is inhaled during the process and used by cells in the body to generate energy through the breakdown of glucose. Carbon dioxide is produced as a waste product and exhaled.
Nitrogen does not get used during breathing. It makes up about 78% of the air we breathe in, but our bodies do not utilize it for any physiological processes. Oxygen is the key gas we inhale for cellular respiration.
the gas that is used is oxygen
it is used in the Kreb's cycle and becomes CO2

Carbon Dioxide
you need oxygen for respiration. Respiration is the process of inhaling and exhaling and releasing energy from glucose and oxygen
During respiration, carbon dioxide gas is released as a byproduct of cellular metabolism. This occurs during the process of breaking down glucose to produce energy in the form of ATP. Carbon dioxide is then exhaled out of the body through the lungs when we breathe.
The gas that is formed during respiration is carbon dioxide. Humans breathe in a mixture of nitrogen, oxygen and carbon dioxide. Although, only oxygen is used. When humans exhale they release all of the nitrogen and more carbon dioxide than was inhaled.
