What else can I help you with?
Where does the electron transport chain get the high-energy electrons that are passed down the chain?
The high-energy electrons in the electron transport chain are derived from molecules like NADH and FADH2, which are generated during cellular respiration in processes like glycolysis and the citric acid cycle. These molecules donate their electrons to the chain, where they are passed down through a series of protein complexes to generate ATP.
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.
During aerobic respiration what directly donates electrons to the electron transport chain at the lowest energy level?
NADH and FADH2 donate electrons to the electron transport chain at the lowest energy level during aerobic respiration. These molecules are produced during earlier stages of cellular respiration (glycolysis and the citric acid cycle) and deliver high-energy electrons to the electron transport chain for ATP production.
How many electrons can the inner shell of an atom contain?
The very inner shell of an atom is the 1st shell and can only contain 2 electrons.
What electron carriers are produced in the Krebs cycle?
There are two electron carriers produced in the citric acid (Krebs Cycle). The first is NAD+ or NADH in its reduced form. The other is FAD+ which becomes FADH2 after being reduced. One turn of the citric acid cycle produces 1 and 3 molecules of FADH2 and NADH respectively.
Where does the electron transport chain get its electrons from?
it gets electrons[2 eletrons from NADH and 2 electrons from FADH2] from NADH and FADH2....In case of NADH- it is directly from glycolysis but in case of FADH2-it is not directly attached to ETC but succinate is oxidised to fumarate realising FADH2
Is FADH2 an electron acceptor?
No, FADH2 is in the "accepted" state. FADH+ is the form of the molecule that is able to accept electrons.
What carries electrons to the electrons transport chain?
The answer is NADH and FADH2. Both of these are electron carriers.
Electrons are brought to the electron transport by what high energy electron carriers?
Electrons are brought to the electron transport chain by high-energy electron carriers such as NADH and FADH2. These carriers donate electrons to the chain, which is then used to generate ATP through oxidative phosphorylation.
What does FADH2 do in ETC?
FADH2 is an electron carrier similar to NADH, but only the second protein in the ETC accepts FADH2 electrons. So FADH2 is used in the ETC, but it produces less ATP due to it only entering the second protein in the ETC.
How many electrons does promethium contain?
The neutral atom of promethium contain 61 electrons.
What molecule are the main electrons carriers of Krebs cycle?
NADH and FADH2
What molecules are the main electrons carriers of the Krebs cycle?
NADH and FADH2

What does NADH and FADH2 power?
NADH and FADH2 are electron carriers that power the electron transport chain in cellular respiration. This process generates ATP, the cell's main energy currency, by transferring electrons from NADH and FADH2 to molecular oxygen.
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.
The accompanying figure shows the electron transport chain what is the combination of substances that is initially added to the chain?
The combination of substances that is initially added to the electron transport chain is NADH and FADH2. These molecules carry electrons from previous steps in cellular respiration to the electron transport chain, where they donate their electrons to the chain to generate ATP.
