During plant respiration, which gas is consumed?

Explanation:
Oxygen is the gas consumed. In plant respiration, cells use oxygen to oxidize sugars and release stored energy as ATP. This process happens mainly in mitochondria and produces carbon dioxide and water as byproducts. Because oxygen is the reactant that combines with the fuel to drive the energy-releasing reactions, it is taken in and used. Carbon dioxide is actually released, not consumed, during respiration. Nitrogen isn’t a driver of this energy process, and hydrogen isn’t consumed as a separate gas in respiration (it becomes part of the water produced).
