how many atp molecules are produced in electron transport chain?
162196
A total of 32 ATP molecules are generated in electron transport and oxidative phosphorylation.
614678
The oxidation of one molecule of NADH thus leads to the synthesis of three molecules of ATP, whereas the oxidation of FADH2, which enters the electron transport chain at complex II, yields only two ATP molecules.

Electron transport chain. The electron transport chain is the last stage of the respiration pathway. It is the stage that produces the most ATP molecules. The electron transport chain is a collection of carrier proteins found on the inner membrane of mitochondria.
308068
One molecule of NADH can yield three ATP and one molecule of FADH2 can yield two ATP. These numbers are not exact because an approximate number of H+ ions is required to move across the inner mitochondrial membrane for the synthesis of each molecule of ATP.
362813
For every pair of electrons transported to the electron transport chain by a molecule of NADH, between 2 and 3 ATP are generated. For each pair of electrons transferred by FADH2, between 1 and 2 ATP are generated.

The total energy gained from the complete breakdown of one (six-carbon) molecule of glucose by glycolysis, the formation of 2 acetyl-CoA molecules, their catabolism in the citric acid cycle, and oxidative phosphorylation equals about 30 ATP molecules, in eukaryotes.
564238
The electron transport chain is located on the inner membrane of the mitochondria, as shown below. The electron transport chain contains a number of electron carriers. These carriers take the electrons from NADH and FADH2, pass them down the chain of complexes and electron carriers, and ultimately produce ATP.

Key Takeaways: Electron Transport Chain The electron transport chain is a series of protein complexes and electron carrier molecules within the inner membrane of mitochondria that generate ATP for energy. Electrons are passed along the chain from protein complex to protein complex until they are donated to oxygen.

The electron transport chain produces 28 ATP molecules. Since 4 ATP molecules were produced earlier in the cellular respiration process, this means...

Explanation: Electron transport chain produces most of ATP. (34) In Eukaryotes ETC occurs in inner membrane of mitochondria. But prokaryotes doesn't have mitochondria which is a membranes bound organelle.
56934
The process of forming ATP from the electron transport chain is known as oxidative phosphorylation. Electrons carried by NADH + H+ and FADH2 are transferred to oxygen via a series of electron carriers, and ATPs are formed. Three ATPs are formed from each NADH + H+, and two ATPs are formed for each FADH2 in eukaryotes.
114852
Glycolysis produces 2 ATP molecules, and the Krebs cycle produces 2 more. Electron transport begins with several molecules of NADH and FADH2 from the Krebs cycle and transfers their energy into as many as 34 more ATP molecules.

The electron transport chain is a process that moves hydrogen ions across a membrane to produce large amounts of ATP. The final step in transferring the energy of sunlight and glucose to the usable energy of ATP takes place during the electron transport chain.

The respiratory chain, otherwise known as the electron transport chain, resides in the mitochondria. A single molecule of NADH has sufficient energy to generate three ATP molecules from ADP.
234292
The electron transport chain is the last stage of the respiration pathway. It is the stage that produces the most ATP molecules. The electron transport chain is a collection of carrier proteins found on the inner membrane of mitochondria. NADH release the hydrogen ions and electrons into the transport chain.

Is any ATP produced in the electron transport chain? No ATP is produced in the electron transport chain. ... The name of the embedded protein that provides a channel for the hydrogen ions to pass through the membrane is ATP synthase. The flow of hydrogen ions through the protein channel provides free energy to do work.
