What happens to the electrons carried by N.A.D.H. andF.A.D.H molecules produced during the citric acid cycle?

Answer 1

It is used to transport hydrogen to the electron transport chain.

Answer 2

these carrier molecules pass 2 energized electrons each, along to the electron transport chain in the inner membrane of the mitochondrion. i hope this helps you. :D

NADH +H^+ ==> the electron came from these electron carrier molecules are transferred to cytochrome system and more specifically cytochrome complex I (also known as NADH-ubiquinone oxidoreductase), and from there it will get transferred to another electron carrier molecule ubiquinone, the electron will keep traveling down to another 2 cytochrome complexes (III and IV) and finally the electron will get transferred to molecular oxygen to form water.

Now this process is taking place in the inner mitochondrial membrane where the electron transport chain is taking place. this is also the site where the proton molecules are diffusing into the intermembrane of the mitochondria.

As for FADH2, its electron will travel as slightly different path, instead going to complex 1 it will get transferred to Complex II which is also known as succinate dehyudrogenase complex. from there the electron will get transferred to complex III to complex IV and finally to oxygen molecule to from water.

the next result of this process is the formation of ATP via protomotive force that is driven by the transfer of both the proton (H^+) and the e^- that was being carried by NADH and FADH2.

i hope this help

Answer 3

NADH and FADH2 are both utilized in the Electron Transport Chain, or ETC. They are both electron carriers. Through a series of enzymes, the Hydrogen atoms are stripped off of the carriers and sent through the membrane to form an electron gradient. These electrons are channeled through another enzyme to produce ATP.

Answer 4

NADH and FADH2 deliver energized electrons at the top of the electron transport chain. The elcetrons are passed from protein to protein within the membrane, slowly releasing their energy in steps.

Some of that energy is is used directly to form ATP; some is used by an enzyme to pump H+ ions into the center of the mitochondrian.

Answer 5

They are sent to other cycles and processes that need their electons.

Answer 6

NADH2 and FADH2 are electron carriers found in the cell. Every molecule of either NADH2 or FADH2 is converted to ATP molecules during cellular respiration.

Answer 7

They are used in electron transport chain along with protons to produce ATP and water.
