what does electron transport chain happens?

The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water.

Figure 1. The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular oxygen. ... Note, however, that the electron transport chain of prokaryotes may not require oxygen as some live in anaerobic conditions.

Glycolysis occurs in the cytosol, but the Krebs cycle and electron transport chain occur inside the mitochondria. Electron carriers such as NADH produced during glycolysis and the Krebs cycle pass their electrons to the electron transport chain, which results in synthesis of a lot of ATP. Figure 6.

The electron transport chain is built up of peptides, enzymes, and other molecules. The flow of electrons through the electron transport chain is an exergonic process. The energy from the redox reactions create an electrochemical proton gradient that drives the synthesis of adenosine triphosphate (ATP).

Explanation: The electron transport chain is used to pump protons into the intermembrane space. This establishes a proton gradient, allowing protons to be pumped through ATP synthase in order to create ATP. This method of ATP production is called oxidative phosphorylation.

The respiratory chain, otherwise known as the electron transport chain, resides in the mitochondria. ... The chain consists of a series of electron carriers which can accept and then donate electrons, while the resulting production of energy is used to stimulate the formation of ATP via oxidative phosphorylation.

Electron carriers are reduced during glycolysis and the citric acid cycle to NADH + H+ and FADH2. These carriers then donate electrons and protons to the electron carrier proteins of the electron transport chain. The final electron acceptor is oxygen. Together with oxygen, electrons and protons form molecules of water.

Key Takeaways: Electron Transport Chain The electron transport chain is a series of protein complexes and electron carrier molecules within the inner membrane of mitochondria that generate ATP for energy. Electrons are passed along the chain from protein complex to protein complex until they are donated to oxygen.

The mitochondrial electron transport chain is a series of enzymes and coenzymes in the crista membrane, each of which is reduced by the preceding coenzyme, and in turn reduces the next, until finally the protons and electrons that have entered the chain from either NADH or reduced flavin reduce oxygen to water.

Overview: oxidative phosphorylation The electron transport chain is a series of proteins embedded in the inner mitochondrial membrane. ... Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.

The electron transport chain uses the high-energy electrons from glycolysis and the Krebs cycle to convert ADP to ATP. ... The electron transport chain uses the high-energy electrons from glycolysis and the Krebs cycle to convert ADP into ATP.

The process of forming ATP from the electron transport chain is known as oxidative phosphorylation. Electrons carried by NADH + H+ and FADH2 are transferred to oxygen via a series of electron carriers, and ATPs are formed. Three ATPs are formed from each NADH + H+, and two ATPs are formed for each FADH2 in eukaryotes.

stage 2 (ETC) (electron transport chain) - (this stage happens after the Kreb's Cycle) if oxygen is present, Hydrogen ions are pumped into inner mitochondrial compartment (this is active transport) Hydrogen ions diffuse back out through a carrier protein giving energy to make ATP (passive transport) Each time a H+ ion ...

Is any ATP produced in the electron transport chain? No ATP is produced in the electron transport chain. ... The name of the embedded protein that provides a channel for the hydrogen ions to pass through the membrane is ATP synthase. The flow of hydrogen ions through the protein channel provides free energy to do work.

The Electron Transport System also called the Electron Transport Chain, is a chain of reactions that converts redox energy available from oxidation of NADH and FADH2, into proton-motive force which is used to synthesize ATP through conformational changes in the ATP synthase complex through a process called oxidative ...
