The electron transport chain is a cluster of proteins that transfer electrons through a membrane within mitochondria to form a gradient of protons that drives the creation of adenosine triphosphate (ATP). ATP is used by the cell as the energy for metabolic processes for cellular functions.

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

The electron transport chain produces adenosine triphosphate, the main cellular energy. Oxygen acts as a final electron acceptor that helps move electrons down a chain that results in adenosine triphosphate production.

At the end of the electron transport chain involved in aerobic respiration, the last electron carrier in the membrane transfers 2 electrons to half an oxygen molecule (an oxygen atom) that simultaneously combines with 2 protons from the surrounding medium to produce water as an end product (Figure 5).

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 is located in the mitochondria. There are five main protein complexes in the electron transport chain, located in the inner membrane of the mitochondria.

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.

Electron Transport Chain. The electron transport chain is the final component of aerobic respiration and is the only part of glucose metabolism that uses atmospheric oxygen. Electron transport is a series of redox reactions that resemble a relay race.

The electron transport chain is built up of peptides, enzymes, and other molecules. The flow of electrons through the electron transport chain is an exergonic process. The energy from the redox reactions create an electrochemical proton gradient that drives the synthesis of adenosine triphosphate (ATP).

Photosynthesis: Water is broken down to oxygen to release electrons for an electron transport chain. Electrons from the transport chain are taken up by hydrogen carriers (NADPH specifically) Uses the Calvin cycle to synthesise glucose (requires hydrogen carriers and carbon dioxide)

Chlorophyll, which is present in the photosystems, soaks up light energy. The energized electrons are then used to make NADPH. The electron transport chain is a series of molecules that accept or donate electrons easily.

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. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water.

Electron Transport Chain. The electron transport chain (aka ETC) is a process in which the NADH and [FADH2] produced during glycolysis, β-oxidation, and other catabolic processes are oxidized thus releasing energy in the form of ATP. The mechanism by which ATP is formed in the ETC is called chemiosmotic phosphorolation ...

What is the main purpose of the electron transport chain? The main purpose of the electron transport chain is to build up a surplus of hydrogen ions (protons) in the intermembrane space so that there will be a concentration gradient compared to the matrix of the mitochondria.
