Open and close an oxygen valve on a cutaway 3D mitochondrion and a close-up of its inner membrane to watch electrons flow along the electron transport chain, H⁺ build up in the intermembrane space and ATP synthase turn. Count ATP per glucose from substrate-level and oxidative phosphorylation, follow each stage from glycolysis to oxidative phosphorylation, and compare aerobic respiration with lactic acid and alcoholic fermentation.
