Electron Transport Chain (overview) • The NADH and FADH2, formed during glycolysis, β-oxidation and the TCA cycle, give up their electrons to reduce molecular O2 to H2O. • Electron transfer occurs through a series of protein electron carriers, the final acceptor being O2; the pathway is called as the electron transport chain. The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis. In the former, the electrons come from breaking down organic molecules, and energy is released. The electron transport chain (ETC) The ETC is responsible for the reduction of molecular oxygen by NADH. This exergonic process (electrons from NADH enter at a relatively low E°′, and electrons exit at relatively high E°′ as they reduce O 2 to H 2 O. making ΔE°′ positive, and thus ΔG°′ is negative) is carried out in a precisely controlled, multistep manner that preserves much of ...

Electron Transport Chain Steps Explained with Diagram. The electron transport chain is an essential metabolic pathway that produces energy by carrying out a series of redox reactions. This BiologyWise article provides a simple explanation of this pathway. The electron transport chain has two essential functions in the cell: Regeneration of electron carriers: Reduced electron carriers NADH and FADH 2 pass their electrons to the chain, turning them back into NAD + and FAD. This function is vital because the oxidized forms are reused in glycolysis and the citric acid cycle (Krebs cycle) during cellular respiration.
