Co2 or carbon dioxicide
Oxygen is the gas that is required for respiration.
Carbon dioxide is the gas that builds up in the body and increases respiration. As levels of carbon dioxide rise, receptors in the bloodstream signal the brain to increase the rate of breathing in order to expel the excess carbon dioxide from the body.
Oxygen is the gas in the atmosphere that is important for respiration. It is needed by cells to generate energy through the process of cellular respiration.
oxygen gas
The gas that is a reactant in aerobic cellular respiration is oxygen. C6H12O6 + O2 --> CO2 + H2O
For cellular respiration you need oxygen.
The main gas produced in aerobic respiration is carbon dioxide (CO2).
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
Anaerobic respiration occurs in the absence of oxygen.
Carbon dioxide is created during respiration.
