[Verse] Inhale the air, feel the oxygen rush Essential for life, it's the breath we all trust Cells in our body, they're working so hard With every breath, they're playing their part [Chorus] Oxygen, the key to respiration Fueling our cells, with every inspiration Electron flow, a journey so bright In the absence of oxygen, a new path takes flight [Verse 2] Glycolysis breaks down the glucose we consume Producing ATP, with a little less room Then comes the Krebs cycle, spinning around Releasing electrons, without a sound [Bridge] Electrons on the move, passing along Through the ETC, where they belong But in the absence of oxygen, a different path they find Fermentation, a new way to unwind [Chorus] Oxygen, the key to respiration Fueling our cells, with every inspiration Electron flow, a journey so bright In the absence of oxygen, a new path takes flight [Outro] So let's celebrate the breath of life And how our cells thrive in the oxygen's light [Ending] (Instrumental play-out)
