Why 3 ATP are produced from one NADH but only 2 ATP from one FADH 2?

So for a real answer...
The electron transport chain basically pumps out protons across the mitochondrial membrane from the matrix into the inter-membrane space, building a proton gradient. When these protons try to flow back in, they run through the ATPase and generate ATP. We can visualize this process as a chain, where electrons move through components of the chain and eject protons as they go from structure to structure.
We generally think of the beginning of this chain as the place where NADH is oxidized and gives up its electrons. However, FADH2 enters from an area which can be thought of as further down the chain. So if we think of the electron transport chain as having three steps, with each step generating one ATP, then NADH starts at step one, but FADH enters the chain later at step two. So FADH will only eject enough protons for two ATP, while NADH ejects enough for three.
That's a simple way of looking at it, at least.

∙ 14y agoWhen NADH releases the electron at the electron transport chain, it starts from complex I, which allows more ATP molecules to be produced as electron goes through. On the contrary, the FADH molecule releases their electron at the complex II, or "Q".
This results in less ATP molecules to be produced.

How many ATP molecules are produced after one complete process of aerobic cellular respiration?
19
What happens to the electrons carried by N.A.D.H. andF.A.D.H molecules produced during the citric acid cycle?
It is used to transport hydrogen to the electron transport chain.
How many ATP are produced in each step of cellular respiration?
Glycolysis produces 4 ATPs but it uses 2 in the process so you are left with 2.The electron transport chain produces 36 ATPs.
What does mitchondrion do?
Stores atp.
Which stage of cellular respiration produces the most ATP?
The Electron Transport process is the third process in cell respiration, it requires oxygen directly. The electron transport "chain" is a series of electron carriers in the membrane of the mitochondria. Through a series of reactions, the "high energy" electrons are passed to oxygen. In the process, a gradient is formed, and ultimately ATP (Adinosine triphosphate), an energy molecule is formed.Therefore this stage produces the most ATP.
What energy is produced by cellular respiration?
NADH,FADH,ATP are produced.Finally all are used to generate ATP.
What energy containing molecule is produced by cellular respiration?
NADH,FADH,ATP are produced.Finally all are used to generate ATP.
Which chemical is responsible for the production of ATP from your food?
Cytochrome complex NADH FADH N i ^^ ER
How many ATP's come from one FADH2's?
Two ATP molecules are produced from one FADH2 going through the electron transport chain. For every NADH, three ATP molecules are produced.
What energy-carrierz molecules are produced by glycolysis?
Nadh and ATP
How many ATP molecules are produced for every pyruvic acid molecule that enters the Krebs' cycle?
The energy tally from one molecule of pyruvic acid is 4 NADH, 1 FADH₂ and 1 molecule of ATP.
Does glycolosis release a lot of energy?
No. Only 2 net ATP and 2 net NADH are produced through glycolysis. The Krebs cycle is where a lot of NADH is produced and then the electron transport chain is where a lot of ATP is produced. These are the stages that release a lot of energy.
What energy carrier is produced during glycolysis?
There are a few energy carrier produced during Glycolysis but NADH and ATP are most produced.
What energy-carrier molecules are produced by glycolysis?
NADH and ATP
How many molecules of ATP are produced during one circuit of the Krebs cycle?
1 This isn't even technically true. One GTP molecule is produced which produces one ATP molecule. The Krebs cycle produces tons of energy, but not in the form of ATP directly. The Krebs cycle (or TCA cycle) results in reducing potential molecules; NADH and FADH2 specifically. These molecules are shuttled through the electron transport chain to produce energy. 3 NADH molecules and 1 FADH molecule is produced for every turn of the Krebs cycle. One molecule of glucose will result in two turns of the Krebs cycle because two pyruvate molecules are the result of one glucose molecule (pyruvate if fed into the Krebs cycle after it is converted into acetyl-CoA). So, one glucose molecule = 6 NADH and 2 FADH molecules (and 2 GTP molecules) In the electron transport chain 1 NADH molecule = 3 ATP. 1 FADH2 molecule = 2 ATP. From here the math is pretty straight forward 6 NADH molecules = 18 ATP 2 FADH molecules = 4 ATP 2 GTP molecules = 2 ATP If you ever read something saying the number of ATP molecules produced from a glucose molecule is between 30-38 ATP do not be confused. This is simply the number for: glycolysis, TCA cycle, and oxidative phosphorylation (electron transport chain) added together. We only get about 30 ATP molecules out of it though because the process is not perfect. Source: Biomed degree.
What energy-carriers molecules are produced by glycolysis?
NADH and ATP
What is the significant of glycolysis?
Glycolysis is the first step in making ATP through cellular respiration. Glycolysis is broken down into pyruvate which is made into Acetyl(sp?) CoA when it goes through the mitochondrial membrane. This change creates molecules called NADH. NADH goes through the citric acid cycle which produces FADH. The NADH and the FADH carry electrons to the electron transport chain which produces ATP through phosphorylation(sp?). So.... With the process of glycolysis, your body produces ATP which allows you to live.
