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


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.


What carries electrons to the electrons transport chain?

The answer is NADH and FADH2. Both of these are electron carriers.


Which molecules donate electrons to the electron transport chain?

Molecules that donate electrons to the electron transport chain include NADH and FADH2, which are produced during glycolysis and the citric acid cycle. These molecules transfer their electrons to protein complexes in the electron transport chain, ultimately leading to the production of ATP through oxidative phosphorylation.


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 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


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.


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.


What part of glucose molecule provides electrons in cellular respiration?

hydrogen from the NADH and FADH2


What molecules carry high-energy electrons into the electron transport chain?

NADH and FADH2 are the molecules that carry high-energy electrons into the electron transport chain. These molecules are produced during glycolysis and the citric acid cycle and donate their electrons to the chain to generate ATP through oxidative phosphorylation.


What are fadh2 and nadh classified as?

FADH2 and NADH are classified as electron carriers in cellular respiration. They play a key role in transferring electrons to the electron transport chain, where the energy from these electrons is used to generate ATP through oxidative phosphorylation.
