how many net atp are made in electron transport chain?
128469
This accounts for about two ATP molecules. A total of 32 ATP molecules are generated in electron transport and oxidative phosphorylation.
741893
During the process of Krebs cycle 2 molecules of ATP, 8 molecules of NADH and 2 molecules of FADH2 were produced per molecule of glucose. A total of 28 ATPs are produced during Krebs cycle per a glucose molecule.

The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.

In addition to ATP, the Krebs cycle produces high-energy FADH2 and NADH molecules, which provide electrons to the oxidative phosphorylation process that generates more high-energy ATP molecules. For each molecule of glucose that is processed in glycolysis, a net of 36 ATPs can be created by aerobic respiration.

Describe the components, organization, and functions of an electron transport system. ATP is composed of ribose, a five-carbon sugar, three phosphate groups, and adenine , a nitrogen-containing compound (also known as a nitrogenous base).

Answer: A sum of 10 NADH's is made (in glucolysis and the Krebs cycle) per glucose, and 2 FADH2's. We by and large state that you get 3 ATPs for each NADH and 2 for every FADH2, with the goal that these transporters produce an aggregate of 30+4 = 34 ATPs.

In this mechanism, NADH reduces a compound in the cytosol, which then is able to cross the membrane into the matrix, where it regenerates NADH by reducing NAD+. The NADH donates electrons to the ETC where it can generate 3 ATP, so that 38 ATP are produced per glucose molecule.

ATP Yield. In a eukaryotic cell, the process of cellular respiration can metabolize one molecule of glucose into 30 to 32 ATP. The process of glycolysis only produces two ATP, while all the rest are produced during the electron 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.
467585
2.5 ATP/NADH and 1.5 ATP/FADH2 are produced in the electron transport chain. Some resources will say 3 ATP/NADH and 2 ATP/FADH2, but these values are generally less accepted now.
28990
In the mitochondria, the metabolism of sugars is completed, and the energy released is harnessed so efficiently that about 30 molecules of ATP are produced for each molecule of glucose oxidized.

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. All told, then, up to 38 molecules of ATP can be produced from just one molecule of glucose in the process of aerobic respiration.

In a eukaryotic cell, the process of cellular respiration can metabolize one molecule of glucose into 30 to 32 ATP. The process of glycolysis only produces two ATP, while all the rest are produced during the electron transport chain.

There is a theoretical maximum of 38 ATP produced from a single glucose molecule: 2 NADH produced in glycolysis (3 ATP each) + 8 NADH produced in Krebs cycle (3 ATP each) + 2 FADH2 produced I don't know where (2 ATP each) + 2 ATP produced in the Krebs cycle + 2 ATP produced in glycolysis = 6 + 24 + 4 + 2 + 2 = 38 ATP, ...

This potential is then used to drive ATP synthase and produce ATP from ADP and a phosphate group. Biology textbooks often state that 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).

In Summary: Electron Transport Chain The electron transport chain is composed of four large, multiprotein complexes embedded in the inner mitochondrial membrane and two small diffusible electron carriers shuttling electrons between them. ... The end products of the electron transport chain are water and ATP.

The electron transport chain is the final step of cellular respiration where 34 ATP molecules are produced.
