Think of it like this: Every time the electron is handed to another cytochrome, it pumps H+ across a membrane to create a gradient. NADH sticks the electron in higher up the chain than FADH2 does so the NADH electron pumps more protons since it is passed between more cytochromes than the FADH2 electrons. Since every proton pumped across is an ADP-->ATP reaction, the more protons an electron can pump, the more energy you get from that electron. FADH2 is around because it has roles in other areas like synthesis, so by being a little more multifunctional than NADH it sacrifices some in the electron transport role.

What molecules are the main electrons carriers of the Krebs cycle?
NADH and FADH2
What molecule's are the main electron carriers of the Krebs cycle?
NADH and FADH2
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 is the product from the Krebs cycle?
NADH
How many ATP can be made from 1 NADH and 1 FADH2?
4 ATP molocules are made from 1 NADH and 1 FADH2 MO
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 is generated by the Kreb cycle?
FADH2 and NADHIt gives four products.They are ATP,CO@, FADH2 and NADH
What process uses NADH and FADH2 to produce ATP?
Glycolysis
What molecules are the main carriers of the Krebs cycle?
NADH and FADH2
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.
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.
What are the energy - containing products of glycolysis?
ATP, NADH, FADH2, and CO2
What molecule are the main electron carriers of the Krebs cycle?
NADH and FADH2
What molecule's are the main electron carriers of the Krebs cycle?
