Oxygen (O2) is the electron acceptor in the Electron Transport Chain.
"The electrons are passed to O2, the final electron acceptor of the electron transport system. This oxygen, now negatively charged because it has acquired additional electrons, combines with H+ ions, which are positively charged because they donated electrons at the beginning of the electron transport system, to form H2O." (Sherwood 36)

Transport chain series of proteins embedded in a membrane along which energized electrons are transported as electrons are passed from molecule energy is released?
Transport chain series of proteins embedded in a membrane along which energized electrons are transported as electrons are passed from molecule energy is released?
High-energy electrons from NADH and FADH2 are passed into and along the?
Electron Transport Chain
What happens to the energy level as electrons are passed along in electron transport?
They begin to electrolyze, a term used for giving off static charge.
Why do organisms need a final electron acceptor?
A final electron acceptor that is a stronger oxidizing agent than the last oxidizing agent in the electron transport chain is needed to remove low-energy electrons from the chain so that new high energy electrons can enter the chain to generate more ATPs. Without a final electron acceptor the electron transport chain will be backed up with low energy electrons and eventually no ATP can be generated since no new electron can enter the chain.
What happens to electrons when pigments in photosystem II absorbs light?
they move through an electron transport chain to photosystem 1
How many electrons can a NADH molecule carry?
The electron transport chain is also known as the respiratory chain. NADH carries electrons in the form of hydrogen atoms to the electron transport chain.
Series of electron acceptors in the thylakoid membrane that removes energy from excited electrons to produce ATP?
Electron transport chain.
What happens as the electrons are passed along the electron carries in the electron transport chain?
Hydrogen ions are pumped across the mitochondria's inner membrane producing a concentration gradient
Do the energized electrons at the primary electron acceptor flow to the reaction center?
No, the electrons flow from the reaction center to the primary electron center. Just the opposite of what you said.
Transport chain series of proteins embedded in a membrane along which energized electrons are transported as electrons are passed from molecule energy is released?
Transport chain series of proteins embedded in a membrane along which energized electrons are transported as electrons are passed from molecule energy is released?
What does the electron transport chain use the high energy electrons for the Krebs cycle for?
The electrons are passed down the electron transport chain for use in ATP production.
Energized electrons at the primary electron acceptor flow to where?
an electron transport chain.
High-energy electrons from NADH and FADH2 are passed into and along the?
Electron Transport Chain
What happens to the energy level as electrons are passed along in electron transport?

What role do high-energy electrons play in the electron chain?
The electron transport chain uses the high-energy electrons from the Krebs cycle to convert ADP into ATP.
Where does the electron transport chain get high energy electrons that are passed down the chains?
High-energy electrons from NADH and FADH2 are passed along the electron transport chain
