Electron Transport Chain. A sequence of electron carrier molecules (membrane proteins) that shuttle electrons during the redox reactions that release energy used to make ATP.

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.

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.

This accounts for about two ATP molecules. A total of 32 ATP molecules are generated in electron transport and oxidative phosphorylation.

The electron transport chain consists of a series of electron carriers that eventually transfer electrons from NADH and FADH2 to oxygen. The chemiosmotic theory states that the transfer of electrons down an electron transport system through a series of oxidation-reduction reactions releases energy.

In Summary: Electron Transport Chain The electron transport chain is the portion of aerobic respiration that uses free oxygen as the final electron acceptor of the electrons removed from the intermediate compounds in glucose catabolism. ... These same molecules can serve as energy sources for the glucose pathways.

The electron transport chain, and site of oxidative phosphorylation is found on the inner mitochondrial membrane.

Explanation: The electron transport chain is primarily used to send protons across the membrane into the intermembrane space. This create a proton-motive force, which will drive ATP synthase in the final step of cellular respiration to create ATP from ADP and a phosphate group.

The main difference between substrate level phosphorylation and oxidative phosphorylation is that substrate level phosphorylation is a direct phosphorylation of ADP with a phosphate group by using the energy obtained from a coupled reaction whereas oxidative phosphorylation is the production of ATP from the oxidized ...

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.

< Biochemistry. The electron transport chain is a system of molecules through which electrons are transferred to generate ATP. It has an important role in both photosynthesis and cellular respiration.

Oxidative phosphorylation is made up of two closely connected components: the electron transport chain and chemiosmosis. In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient.

Electrons are transferred to O2 only if ADP is concomitantly phosphorylated to ATP. The regulation of the rate of oxidative phosphorylation by the ADP level is called respiratory control or acceptor control. The level of ADP likewise affects the rate of the citric acid cycle because of its need for NAD+ and FAD.

Figure 1. The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular oxygen. ... The common feature of all electron transport chains is the presence of a proton pump to create a proton gradient across a membrane.
