This is the blockbuster movie of cellular respiration. All those NADH and FADH₂ tokens you collected? They’re now VIP tickets to the electron transport chain (or ETC, for short). This happens on the inner membrane of the mitochondria, like a high-tech factory line.
The electrons get passed from one protein to the next, like a game of hot potato. With each pass, they lose a little energy, which the cell uses to pump protons (tiny hydrogen ions) across the membrane. It creates a concentration gradient—like a dam holding back water.

And then comes the crowning moment: oxygen finally shows up. That oxygen you breathe in grabs the electrons at the end of the chain and swoops in to save the day. It forms water (yes, you make water inside you!). That dam of protons then rushes back through a little turbine called ATP synthase, and it cranks out ATP like a factory on max speed. We’re talking about 34 ATP from this single stage. Boom!
