What else can I help you with?
What accepts the electrons at the end of the electron transport chain?
Oxygen accepts the electrons at the end of the electron transport chain, ultimately forming water.
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.
What atom accepts electrons at the of the electron transport chain?
The atom that accepts electrons at the end of the electron transport chain is oxygen. Oxygen acts as the final electron acceptor in aerobic respiration, combining with electrons and protons to form water.
The electron transport chain receives electrons directly from?
The electron transport chain receives electrons directly from NADH and FADH2, which are produced during the earlier stages of cellular respiration. These molecules donate their electrons to the complex proteins within the electron transport chain, allowing for the creation of a proton gradient that drives ATP production.
Which group of iron-sulfur proteins in the electron transport chain accepts electrons from FADH2?
The iron-sulfur proteins in the electron transport chain that accept electrons from FADH2 are known as Complex II or succinate dehydrogenase.
Where do the electrons originate from in the electron transport chain?
The electrons in the electron transport chain originate from the breakdown of glucose during cellular respiration.
What accepts the electrons at the end of the electron transport chain?
Oxygen accepts the electrons at the end of the electron transport chain, ultimately forming water.
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.
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.
Energized electrons at the primary electron acceptor flow to where?
an electron transport chain.
The attraction of the nucleus for the outer electrons in large atoms is lessened as a result of?
The attraction of the nucleus for the outer electrons in large atoms is lessened as a result of increased electron-electron repulsions. As the number of electrons increases, these repulsions cause the outer electrons to be further away from the nucleus, reducing the effective attraction. This phenomenon contributes to the shielding effect and explains the reduced attraction of the nucleus for outer electrons in large atoms.
Where do the electrons used in the electron transport chain come from?
The electrons used in the electron transport chain come from the breakdown of molecules like glucose during cellular respiration.
Which complex in the electron transport chain transfers electrons to the final electron acceptor?
The complex in the electron transport chain that transfers electrons to the final electron acceptor is called Complex IV, also known as cytochrome c oxidase.
What is the difference between a valence electron and a shielding electron?
Valence electrons are electrons on the outermost shell/orbitals. Sheilding electrons are inner electrons that block valence electrons from protons causing less attraction.
What carries electrons to the electrons transport chain?
The answer is NADH and FADH2. Both of these are electron carriers.
Where do the electrons go after they finish the electron transport chain?
Photosystem I
What is the final acceptor of electrons in the electron transport train?
Oxygen
