Oxygen is crucial for cellular respiration, the process that generates energy in our bodies. Without oxygen, cells cannot produce the energy needed for vital functions, leading to rapid organ failure and death within minutes.
We can survive without food or water for a few days, but we cannot survive without oxygen for even a few minutes. Explain why?

Oxygen is essential for cellular respiration, which is the process that converts nutrients into energy within our cells. Without oxygen, our cells cannot perform this function, leading to a lack of energy required for vital bodily functions. This energy deficit quickly causes critical organs to fail, including the brain, which can lead to unconsciousness and death within minutes. In contrast, while food and water are essential, our bodies can survive longer without them, as they are not immediately critical for energy production.
