The electron transport chain is a series of redox reactions( Oxidation-Reduction) in which electrons are passed from carrier molecules down the chain to ultimately form ATP. The electron transport chain is an energy converter, transforming the chemical energy to the energy of a H+ gradient. As electrons flow along the electrochemical gradient, some of the energy is used by each complex to pump H+ ions from the mitochondrial matrix to the inter-membrane space. These Hydrogen ions create the electrochemical proton gradient that drives them back across the inner membrane through the ATP synthase complex. ATP synthase uses energy of H+ flow(electrical energy) to synthesize ATP from ADP and P. Oxidation of each NADH + H to NAD+ yields 3 ATP. Remember that oxidation is the loss of an electron and reduction is the gain of an electron. Ultimately the purpose of Cellular respiration is to make ATP. The electron transport chain carries out oxidative phosphorylation, which accounts for most of the ATP generated by cellular respiration. A phosphate group is tacked onto ADP to make ATP, using the energy formed from the electrochemical gradient. This pathway has much detail, much more than I've spoke of. Oh, and the Krebs cycle( a simplified version) ...During each turn of the cycle, 2 carbon atoms are removed from the substrates as CO2, 4 oxidations by removal of hydrogen atoms occur, producing four molecules of reduced coenzymes( 3 NADH + H+ and 1 FADH2,) and 1 ATP. The reduced coenzymes produced in the Krebs cylcle are the substrates for the Electron transport chain. These are the electron carriers. Finally, we must remember that Oxygen is required for the Krebs cycle and Electron transport chain and is thus, Aerobic.

∙ 12y agoIn the electron transport chain, electrons are transferred through a series of protein complexes embedded in the inner mitochondrial membrane. These protein complexes, labeled I to IV, use the energy from electron transport to pump protons across the membrane, creating an electrochemical gradient. The energy from this gradient is then used by ATP synthase to generate ATP.

Oxygen is the final electron acceptor in the electron transport chain, which allows for the production of ATP through oxidative phosphorylation. Without oxygen, the electron transport chain cannot function properly, leading to a halt in ATP production and ultimately cell death.
Oxygen accepts the electrons at the end of the electron transport chain, ultimately forming water.
Oxygen has the greatest attraction for electrons in the electron transport chain. It serves as the final electron acceptor, leading to the formation of water.
Oxygen acts as the final hydrogen acceptor in the electron transport chain. It receives electrons and protons at the end of the chain, combining them to form water.
Protons fall down their concentration gradient through the ATP-synthase and are picked up by oxygen, along with electrons, to make water. So, ATP and water " comes out " the electron transport chain.
what is a synonym of the electron transport chain
The electron transport chain is used to make ATP.
The electron transport chain is located in the inner mitochondrial membrane of cells.
Electronic transport chain
No, oxygen is the final electron acceptor of the electron transport chain.
From Glycolysis and Electron Transport Chain
The final reduced species in the electron transport chain is water. Oxygen is the final electron acceptor in the chain, and it is reduced to form water.
ETC---Electron transport chain
The products of the electron transport chain are water and adenosine triphosphate. ATP.
Cyanide binds the electron transport chain at the level of complex IV
The electron transport chain is also known as the respiratory chain.
The series of electron acceptors in the thylakoid membrane is known as the electron transport chain. As electrons move through the chain, they lose energy, which is used to pump protons across the membrane, creating a proton gradient. This gradient is then used by ATP synthase to produce ATP through a process known as chemiosmosis.
