Electron transport chain An electron transport chain (ETC) is a series of compounds that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons (H + ions) across a membrane.n the mitochondrial electron transport chain electrons move from an electron donor (NADH or QH 2) to a terminal electron acceptor (O 2) via a series of redox reactions.

What is an electron transport train? Function? · just now. Report Abuse. The electron transport chain (ETC) is one phase of aerobic cellular respiration. The function of the ETC is the same as the overall goal of cellular respiration, which is to convert the stored energy in food sources (ex. glucose) into energy that can be used by the cells in an organism.

7. Electron Transport Chain and ATP Formation It is used to pump protons (H+) from the mitochondrial matrix into the intermembrane space. The flow of electrons through Complexes I, III and IV is coupled with pumping a certain number of protons per electron pair; Complex II does not pump anything.

Wat is the purpose of the electron transport chain? Best Answer: Well honey, this is a long answer. So sit back, relax and read. The purpose of the electron transport chain is harvesting the energy of the reduced coenzymes NADH and FADH2, which were formed in Glycolysis and the Kreb's cycle. Much of the free energy of these reduced coenzymes is transferred to ATP.ADH and FADH2 that have been formed so far transfer the hydrogen atom electrons they carry to a series of compounds, mainly proteins, which are associated with the inner mitochondrial membrane, called the Electron transport chain.

- Best Answer: Your answer is A. An electron transport chain (ETC) couples a chemical reaction between an electron donor (such as NADH) and an electron acceptor (such as O2) to the transfer of H+ ions across a membrane, through a set of mediating biochemical reactions.

- The electron transport chain is located in the cristae of the inner mitochondrial membrane. The NADH and FADH 2 produced by the citric acid cycle in the matrix release a proton and electron to regenerate NAD + and FAD.

- The electron transport chain is initiated by the reaction of an organic metabolite (intermediate in metabolic reactions) with the coenzyme NAD+ (nicotinamide adenine dinucleotide). This is an oxidation reaction where 2 hydrogen atoms (or 2 hydrogen ions and 2 electrons) are removed from the organic metabolite.

Electron transport chain Sequence of electron transport. In electron transport, electrons from NADH and FADH2 are passed through four complexes (I, II, III, IV) (See Figure 15.10). Complex V depicted in the figure refers to the process of oxidative phosphorylation. The sequence of events in ETS is as follows.

Human Physiology/Print Version (eukaryotes). ​It is easiest to understand how electron transport works by dividing this process into three main events: In the electron transport chain, these electron carriers are oxidized, transferring their electrons to the carrier molecules embedded in the ETC membrane.

What is the electron transport chain? The electron transport chain (ETC) is located in a mitochondrion; in fact the mitochondrion has two membranes around it and the ETC is located within the inner membrane which is folded into cristae to increase the surface area for ATP synthesis.

Electron transport chain The electron transport chain in the mitochondrion is the site of oxidative phosphorylation in eukaryotes. The NADH and succinate generated in the citric acid cycle are oxidized, providing energy to power ATP synthase.lectron transport chains are redox reactions that transfer electrons from an electron donor to an electron acceptor. The transfer of electrons is coupled to the translocation of protons across a membrane, producing a proton gradient. The proton gradient is used to produce useful work.

Oxidative phosphorylation The flow of electrons through the electron transport chain, from electron donors such as NADH to electron acceptors such as oxygen, is an exergonic process – it releases energy, whereas the synthesis of ATP is an endergonic process, which requires an input of energy.

Click here for Posted on. (Answer #1). The role of NADH and FADH2 is to donate electrons to the electron transport chain. They both donate electrons by providing an hydrogen molecule to the oxygen molecule to create water during the electron transport chain. NADH is a product of both the glycolysis and Kreb cycles.uring the electron transport chain, NADH become NAD+ and the H get transported across the membrane. As a result, electrons reduced from NAD+ are used in the transport chain. Similar thing happens to FADH2 as well.

The Electron Transport Chain Steps Simplified The electron transport chain is the final and most important step of cellular respiration. While Glycolysis and the Citric Acid Cycle make the necessary precursors, the electron transport chain is where a majority of the ATP is created.hile the electron transport chain’s main function is to produce ATP, another important byproduct is water. If you follow the path of electrons (blue) and protons(pink) you might notice that they follow the same basic pathway until the point where ATP is produced.
