Best Answer

They are used in the production of ATP, the 'energy currency' of the cell.

FADH2 and NADH have the very important role of being electron carriers for the electron transport chain. Both are used at key points in glycolysis and/or the Kreb's cycle.

FADH2 : Carries electrons in the form of hydrogen atoms (1 proton and 1 electron) with 0 net charge. With 2 hydrogens FAD may use these electrons one at a time or 2 at a time, depending on which ever process it is in.

NADH : Carries it's electrons in the form of hydrides (1 proton and 2 electrons) with -1 net charge. Since these electrons are in the hydride form they both must be used at the same time, there isn't an option to use 1 OR 2 only 2 electrons.

What is NADH and FADH2?

NADH and FADH2 are electron carriers for cells.


Where are NADH and FADH2 produced?

Both NADH and FADH2 are produced in the Krebs Cycle.


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?

What is generated by the Kreb cycle?

FADH2 and NADHIt gives four products.They are ATP,CO@, FADH2 and NADH


Why does nadh produce 3 ATP but fadh2 produce 2 ATP?

NADH produces 3 ATPs because it donates the proton at a "higher" location in the electron transport chain than does FADH2, which is why FADH2 produce only 2 ATPs. NADH and FADH2 donates electrons and protons into the electron transport chain.


What are the functions of NADH and FADH2 in aerobic respiration?

From what I understand of NADH and FADH2, they move electrons from one molecule to another, aerobic respiration (cells creating energy with the use of oxygen). So I would take to guess that NADH and FADH2 help cells create energy effectively.

Why are NADH and FADH2 said to have reducing power?

NADH and FADH2 are electron carriers. They are said to have reducing power because they donate electrons to components of the electron transport chain.


During aerobic respiration what directly donates electrons to the electron transport chain at the lowest energy level?

FADH2 Only FADH2 and NADH donates electrons to the electron chain, and FADH2 donates at a lower level. Hence FADH2 produces less ATP than NADH.

FADH2 and NADH


Where do NaDH and FADH2 take their electrons?

From the oxidation of glucose.


Why more ATP is made per molecule of nadh than per molecule of fadh2?

Fewer protons are pumped across the inner mitochondrial membrane when FADH2 is the electron donor than when NADH is the electron donor.


Why do the electrons carried by fadh2 result in fewer ATP than nadh carriers?

When NADH goes through the electron transport chain it causes three protons to be pumped into the intermembrane space. FADH2 only pumps two. When these protons pass through ATP synthase each makes an ATP. SO NADH makes 3 and FADH2 makes 2.


The primary function of NADH and FADH2 is?
