the electron deliver chain just has actually 3 spots wright here nadh, fadh2, and gtp deserve to feed its electrons. each of those 3 spots (on the electron deliver chain) makes one atp. nadh2 is fed to the initially protien, therefore it goes via all 3 making 3 atp"s. fadh2 skips the initially protien, and deposits its electrons to the second protien, therefore, fadh2"s electrons just go with 2 of the protiens, yielding 2 atp. gtp is feeds its electrons to the third, making just one atp...... remember, nadh2 just provides 3 atp per nadhs as soon as it is making atp via oxidative phosphorylation, in substprice level phos, it provides only 2.
You are watching: Why does fadh2 yield less atp than nadh?
the electron transport chain only has actually 3 spots where nadh, fadh2, and also gtp can feed its electrons. each of those 3 spots (on the electron transfer chain) provides one atp. nadh2 is fed to the first protien, therefore it goes with all 3 making 3 atp"s. fadh2 skips the first protien, and deposits its electrons to the second protien, therefore, fadh2"s electrons just go through 2 of the protiens, yielding 2 atp. gtp is feeds its electrons to the 3rd, making just one atp...... remember, nadh2 only provides 3 atp per nadhs as soon as it is making atp using oxidative phosphorylation, in substrate level phos, it renders just 2.
FADH2 makes less ATP bereason it enters the electron transfer chain at a later phase than does NADH. The electron carry chain is made of carrier molecules assembled into 3 protein complexes, and the passage of an electron with each complicated generates sufficient power to make about 1 ATP per complicated. NADH enters the cycle at the first complex, so NADH produces 3 ATP. FADH2 enters the cycle at the second complex, hence generating 2 ATP. Hope this helps!
Awesome! training for brand-new york marathon in the loss, then boston following april. moving to new england in a few months, so next yr is the perfect opportunity to partake in the boston marathon.

More specfically, FADH2 does not produce 3 ATP bereason its redox potential is only slightly reduced than the complicated in the ETC wright here the electrons from FADH2 enters (Complex II).Remember that the complexes in the ETC go from more negative to even more positive Redox potential as you relocate additionally down the line. This adjust in redox potential is why the ETC can generate an H+ gradient for ATP.So the electrons from NADH travel from NADH --> I --> III --> IV, which is 3 boosts in redox potential (from NADH to I, then I to III, and III to IV)so 3 ATP are produced. (This is exceptionally simplified to make it MCAT relevant).The electrons from FADH2, however, Go from FADH --> Complex II --> Complex III --> Complex IV. In this development tright here are only 2 increases in redox potential (from II to III, and III to IV). The readjust in redox potential in between FADH2 and Complex II isn"t big sufficient to translocate H+ to the IMS. Therefore, there are just 2 ATP created.http://tainano.com/Molecular%20Biology%20Glossary.files/image078.gif
