Final answer:
In the presence of oxygen, cellular respiration converts glucose into carbon dioxide, water, and ATP, through stages including glycolysis, the Krebs cycle, and the electron transport chain.
Step-by-step explanation:
The complete reactions of cellular respiration in the presence of oxygen result in the breakdown of glucose to form carbon dioxide, water, and chemical energy. This process can be summed up by the chemical equation: C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + Energy.
It's important to understand that cellular respiration is not a single step process like combustion, but a complex series of reactions that include glycolysis, the Krebs cycle, and the electron transport chain. Glycolysis occurs in the cytoplasm and does not require oxygen, while the Krebs cycle and electron transport require oxygen and occur in the mitochondria.
During these processes, glucose is oxidized while oxygen is reduced, leading to the formation of carbon dioxide and water. Additionally, a significant amount of ATP is generated, which is used by the cell for various activities.
