What is the role of oxygen gas in our cells?

Answer 1

Oxygen is vital to cellular respiration in the mitochondria.

One sugar molecule can produce 36 ATP energy molecules in the mitochondria when oxygen combines with hydrogen ions, whereas fermentation can only produce three ATP energy molecules from a single sugar molecule.

Similar to what occurs in yeast cells, the "burning" or metabolism of sugars in our cells would not be possible without oxygen.

Answer 2

Oxygen gas plays a crucial role in cellular respiration, where it serves as the final electron acceptor in the electron transport chain, allowing the production of ATP, the energy currency of cells.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
