WebOxidative phosphorylation (UK / ɒ k ˈ s ɪ d. ə. t ɪ v /, US / ˈ ɑː k. s ɪ ˌ d eɪ. t ɪ v /) or electron transport-linked phosphorylation or terminal oxidation is the metabolic pathway in which cells use enzymes to oxidize nutrients, thereby releasing chemical energy in order to produce adenosine triphosphate (ATP). In eukaryotes, this takes place inside mitochondria. WebSpecifically, the number of protons required to form 1 ATP will vary slightly depending on your source. Some textbooks will say you get about 3 ATP per NADH and 2 ATP per FADH2, and obviously this will affect your calculations on how many ATP are ultimately produced.
