WebThere are four protein complexes (labeled complex I-IV) in the electron transport chain, which are involved in moving electrons from NADH and FADH 2 to molecular oxygen. Complex I establishes the hydrogen ion gradient by pumping four hydrogen ions across the membrane from the matrix into the intermembrane space. Web6 aug. 2024 · For every electron transferred to cytochrome c, 2 protons (H+) are pumped into the IMS, resulting in 4H+pumped into the IMS for every electron pair moved through the cycle. Cytochrome c transports electrons to Complex IV where molecular oxygen acts as a terminal electron acceptor and is reduced to water. 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).
