During aerobic respiration what directly donates electrons to the electron transport chain at the lowest energy level?

FADH2 Only FADH2 and NADH donates electrons to the electron chain, and FADH2 donates at a lower level. Hence FADH2 produces less ATP than NADH.

The electron transport chain receives electrons directly from?
NADH
The spent electrons from electron transport in aerobic respiration are transferred to?
Its a take home test?
During aerobic respiration electrons are passed down the electron transport chain and what is formed?
Aerobic respiration is a cellular level process in which nutrients are changed into energy. The electrons that pass down the electron transport chain react with oxygen (thus, aerobic) and protons to form water.
Does anaerobic cellular fermentation use the same final electron acceptors as aerobic respiration?
No, because the electron acceptor is what cates the electrons as the leave the electron transport chain, which is oxygen in aerobic respiration. Since aerobic respiration uses oxygen, and anaerobic fermentation is abest of oxygen, anaerobic fermentation cannot possibly use oxygen as respiration does.
What is the final electron acceptor of the ETC?
In cellular respiration, the final electron acceptor of the electron transport chain is half of a diatomic oxygen molecule. This molecule is then reduced when it gains two low-energy electrons attached to two hydrogens, making a molecule of water as a by-product of cellular respiration.
When are electrons and H ions used in cell respiration?
The Electron Transport System

What molecule lose electrons in cell respiration?
In the third stage of cellular respiration (Electron Transport Chain), electrons are lost from the NADH and FADH2 molecules. These electrons travel down the electron transport chain which is in the inner membrane of the mitochondria and result in being reactants for the formation of H2O.
What two things pass high energy electrons to electron transport chain?
NADH and FADH2 dump electrons into the electron transport chain during cellular respiration.
What is produced when the electrons leave the electron transport chain in cellular respiration and bind to the final electron acceptor for the chain?
Oxygen.
The oxygen consumed during cellular respiration is involved in what process?
Oxygen consumed during cellular respiration is involved in the electron transport chain; it is the final electron acceptor (this is also what makes it either aerobic or anaerobic respiration).
Why is oxygen needed for the final step in cellular respiration?
Oxygen is the final electron acceptor. Oxygen, with it's great electronegativity, pulls electrons through the electron transport chain where these electrons provide the motive force to pump protons into the outer lumen of the mitochondria. When these protons fall down their concentration gradient oxygen is there to pick then up with the electrons and form water.
What parts of the body do the aerobic cellular respiration takes place?
The electron transport chain is the aerobic step of cellular respiration. Oxygen is the last electron acceptor in the electron transport chain. The last step in aerobic respiration is the bonding of 2 electrons, 2 protons, and oxygen to form water. The water leaves the electron transport chain, freeing up a place for another oxygen molecule so that the electron transport chain does not stop.
What is the purpose of the electrons in cellular respiration?
The purpose of electron carriers such as NADH and FADH2 is to dump electrons at the electron transport chain. This creates a proton gradient and allows oxidative phosphorylation to take place.
Which stage of cellular respiration produces the most ATP?
The Electron Transport process is the third process in cell respiration, it requires oxygen directly. The electron transport "chain" is a series of electron carriers in the membrane of the mitochondria. Through a series of reactions, the "high energy" electrons are passed to oxygen. In the process, a gradient is formed, and ultimately ATP (Adinosine triphosphate), an energy molecule is formed.Therefore this stage produces the most ATP.
