The products of the electron transport chains are ATPs and water. Oxygen. Hydrogen ions flow "down" the gradient - from outer to inner compartment - through the ion channel/enzyme ATP synthase, which transfers their energy to ATP. Answer: 1 question Which of the following pass high-energy electrons to the electron transport chain? Electron Transport Chain Electrons from NADH and FADH2 are passed through a series of electron acceptors present in the inner membrane of mitochondria. The electrons originate from water and love along the electron transport chain. Electrons are passed rapidly from one component to the next to the endpoint of the chain, where the electrons reduce molecular oxygen, producing … For more information contact us at [email protected] or check out our status page at https://status.libretexts.org. S. Chand and Company. The electron transport chain is the final component of aerobic respiration and is the only part of glucose metabolism that uses atmospheric oxygen. The name says it all. The electron transport chain is made up of a series of spatially separated enzyme complexes that transfer electrons from electron donors to electron receptors via sets of redox reactions. The electron transport chain (ETC) The ETC is responsible for the reduction of molecular oxygen by NADH. The final electron acceptor in aerobic respiration is molecular oxygen while in anaerobic respiration, it can be sulfate or other molecules. Transfer of electrons from CoQ to cytochrome c c. Transfer of electrons from cytochrome c to molecular oxygen. This stage consists of a series of electron transfer from organic compounds to oxygen while simultaneously releasing energy during the process. (2012) Biochemistry. A prosthetic groupis a non-protein molecule required for the activity of a protein. More specifically, it relates to the generation of ATP by the movement of hydrogen ions across a membrane. It could be used to power oxidative phosphorylation. Nelson DL and Cox MM. The main function of the electron transport chain is the production of ATPs from NADH and FADH. 1% – https://www.youtube.com/watch?v=C8VHyezOJD4, 1% – https://www.sciencedirect.com/topics/engineering/electron-transport-chain, 1% – https://www.ncbi.nlm.nih.gov/gene/1351, 1% – https://www.enotes.com/homework-help/how-much-atps-produced-electron-transport-chain-296899, 1% – https://www.answers.com/Q/What_are_the_products_from_the_electron_transport_chain_pathway, 1% – https://study.com/academy/answer/what-is-the-role-of-oxygen-in-the-electron-transport-chain.html, 1% – https://study.com/academy/answer/what-is-the-main-function-of-the-electron-transport-chain.html, 1% – https://study.com/academy/answer/what-is-the-final-electron-acceptor-in-aerobic-respiration.html, 1% – https://scienceterms.net/biology/electron-transport-chain/, 1% – https://quizlet.com/286346680/electron-transport-chain-and-atp-synthesis-flash-cards/, 1% – https://quizlet.com/21581063/oxidative-phosphorylation-the-electron-transport-chain-part-1-flash-cards/, 1% – https://courses.lumenlearning.com/suny-wmopen-biology1/chapter/cellular-respiration/, 1% – https://courses.lumenlearning.com/ap2/chapter/carbohydrate-metabolism-no-content/, <1% – https://www.youtube.com/watch?v=E_UG3WnsW3o, <1% – https://www.youtube.com/watch?v=Ak17BWJ3bLg, <1% – https://www.sciencedirect.com/topics/biochemistry-genetics-and-molecular-biology/electron-transport-chain, <1% – https://www.sciencedirect.com/science/article/pii/B9780125152501500199, <1% – https://www.researchgate.net/publication/236079479_Mitochondrial_Complex_I, <1% – https://www.ncbi.nlm.nih.gov/books/NBK21208/, <1% – https://www.nature.com/scitable/topicpage/cell-membranes-14052567/, <1% – https://study.com/academy/lesson/mitochondrial-inner-membrane-definition-lesson-quiz.html, <1% – https://science.sciencemag.org/content/283/5407/1488.full, <1% – https://quizlet.com/86969125/electron-transport-chain-flash-cards/, <1% – https://quizlet.com/44325583/week-9-set-2-flash-cards/, <1% – https://quizlet.com/41426337/chapter-7-flash-cards/, <1% – https://quizlet.com/35997625/ch-5-microbial-metabolism-flash-cards/, <1% – https://quizlet.com/323631711/electron-transport-chain-flash-cards/, <1% – https://quizlet.com/193610030/cellular-respiration-electron-transport-chain-and-atp-synthesis-flash-cards/, <1% – https://quizlet.com/178316148/103-the-electron-transport-chain-flash-cards/, <1% – https://quizlet.com/128115137/biochemistry-chapter-20-most-of-it-flash-cards/, <1% – https://quizlet.com/109921003/chapter-18-electron-transport-chain-flash-cards/, <1% – https://quizlet.com/10110889/chapter-6-flash-cards/, <1% – https://hippocampus.org/homework-help/Biology/Plant%20Energetics_Photosystems%20I%20and%20II.html, <1% – https://en.wikipedia.org/wiki/NADH_dehydrogenase_(ubiquinone), <1% – https://courses.lumenlearning.com/wm-biology1/chapter/reading-electron-transport-chain/, <1% – https://ca.wikipedia.org/wiki/Citocrom_c, <1% – https://biologywise.com/function-of-nadh-fadh2, <1% – https://biologydictionary.net/electron-transport-chain/, <1% – https://bio.libretexts.org/Courses/Manchester_Community_College_(MCC)/The_Introduction_to_Microbiology_(Cases)/07%3A_Microbial_Metabolism/7.03%3A_Catabolism_of_Carbohydrates, <1% – https://answers.yahoo.com/question/index?qid=20080704111519AATG8uA, <1% – http://www.dbriers.com/tutorials/2012/04/the-electron-transport-chain-simplified/, <1% – http://acebiochemistry.yolasite.com/proton-gradient-and-atp-synthase.php.
