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.
3 high phosphate bonds on ADP's & 30 ATP's
An electron transport chain (ETC) couples a reaction between an electron donor (such as NADH) and an electron acceptor (such as O2
Plants, fungi, and animals are all eukaryotes and possess mitochondria, which is the site of the electron transport chain. Prokaryotes have no mitochondria and perform the electron transport chain across their cell membranes. Electron transport chain also occurs in thylakoid membrane of chloroplasts.
No, the electrons flow from the reaction center to the primary electron center. Just the opposite of what you said.
NADH
High-energy electrons from NADH and FADH2 are passed along the electron transport chain
When light hits photosytem II (within the thylakoid), it excites electrons which move through the electron transport chain.
