NADH and NADPH from glycolysis, TCA cycle, and other oxidations reduce oxygen to water in mitochondria {respiration, metabolism}. Hydrogen ions increase inside mitochondria and make pH gradient across mitochondrial membrane.
respiratory chain
Aerobic reduction reactions {respiratory chain} make the following compounds: FMNH2 [2 is subscript], ferrous iron, coenzyme Q, cytochrome b, iron-sulfur bond, cytochrome c, cytochrome c1, cytochrome a, cytochrome a3, and water from oxygen.
phosphorylation
Oxidative phosphorylation links to respiratory chain at three places: coenzyme Q reduction, cytochrome c reduction to cytochrome c1, and oxygen reduction to water. At the three steps, respiratory chain places hydrogen ions on mitochondria inner-membrane outside.
poisons
Hydrogen cyanide, carbon monoxide, and hydrogen sulfide inhibit oxygen reduction to water.
