What is the final electron acceptor in electron transport chain?

oxygen
METC transfers electrons from reduced molecules such as nicotinamide adenine dinucleotide (NADH) or succinate—which are produced during oxidation of glucose by glycolysis and by Kreb’s cycle and by beta oxidation of lipids—to oxygen as the final electron acceptor with water as the product.

What is the final electron acceptor in the electron transport chain quizlet?

Oxygen is the final electron acceptor, and it has the highest affinity for electrons. When oxygen accepts an electron, it is reduced to water.

What is the final electron acceptor at the end of the electron transport chain that is then converted into water?

Electron transport is a series of chemical reactions that resembles a bucket brigade in that electrons are passed rapidly from one component to the next, to the endpoint of the chain where oxygen is the final electron acceptor and water is produced.

What is the end result of the electron transport chain?

At the end of the electron transport chain, electrons are transferred to molecular oxygen, which splits in half and takes up H +start superscript, plus, end superscript to form water. Gradient-driven synthesis of ATP.

What does oxygen get reduced to at the end of the electron transport chain?

At the end of the pathway, the electrons are used to reduce an oxygen molecule to oxygen ions. The extra electrons on the oxygen attract hydrogen ions (protons) from the surrounding medium, and water is formed.

Which of the following is the final electron acceptor in oxidative phosphorylation?

Thus, elemental oxygen gets used as the final electron acceptor in oxidative phosphorylation.

What is the final electron acceptor during aerobic respiration quizlet?

Final electron acceptor in aerobic respiration is molecular oxygen.

What are the consequences of diverting electrons from the transport chain?

What are the consequences of diverting these electrons from the transport chain? The intermembrane compartment becomes more acidic. More ATP are generated per glucose molecule. More energy is lost as heat.

Does the electron transport chain require oxygen?

Explanation: Oxygen is the final electron acceptor in the electron transport chain, which allows for oxidative phosphorylation. Without oxygen, the electrons will be backed up, eventually causing the electron transport chain to halt.

What is the relationship between the electron transport chain and oxygen?

Which of the following can be used as a final electron acceptor for aerobic respiration quizlet?

Which of the following can be used as a final electron acceptor for aerobic respiration? – Nitrate ion, sulfate ion, and carbonate ion can all be used as a final electron acceptor. You just studied 94 terms!

What are the end products of oxidative phosphorylation?

-The transfer of an electron to molecular oxygen combines with H+ to form water is marked as an end product in the oxidative phosphorylation pathway. So, the correct answer is, ‘ATP+H2O.

Which is the final acceptor of electrons in the electron transport chain?

The molecules of the chain include peptides, enzymes (which are proteins or protein complexes ), and others. The final acceptor of electrons in the electron transport chain during aerobic respiration is molecular oxygen although a variety of acceptors other than oxygen such as sulfate exist in anaerobic respiration .

How is the electron transport chain built up?

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).

How does the electron transport chain function in oxidative stress?

Electron transport chains are major sites of premature electron leakage to oxygen, generating superoxide and potentially resulting in increased oxidative stress. The electron transport chain consists of a spatially separated series of redox reactions in which electrons are transferred from a donor molecule to an acceptor molecule.

What happens when electrons pass between donor and acceptor?

Passage of electrons between donor and acceptor releases energy, which is used to generate a proton gradient across the mitochondrial membrane by “pumping” protons into the intermembrane space, producing a thermodynamic state that has the potential to do work.
