The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons are passed from one member of the transport chain to another in a series of redox reactions.

Answer and Explanation: The electron transport chain is the third step in aerobic cellular respiration. It is the stage when oxygen is finally used.

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.

Since the electron transport chain is located in the inner mitochondrial membrane in eukaryotes, and since NADH cannot be transported from the cytosol into the mitochondrial matrix, NADH formed in the cytosol needs to be oxidized by another route.

The electron transport chain (ETC) is a series of complexes that transfer electrons from electron donors to electron acceptors via redox (both reduction and oxidation occurring simultaneously) reactions, and couples this electron transfer with the transfer of protons (H+ ions) across a membrane.

The electron transport chain is present in multiple copies in the inner mitochondrial membrane of eukaryotes and in the plasma membrane of prokaryotes.

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.

Where is the electron transport chain found in a eukaryotic cell? ... It is found in the inner membrane of the mitochondrion in eukaryotes and in the cell membrane of prokaryotes. Explain how the products of glycolysis and the Krebs cycle are related to the electron transport chain. NADH is produced in glycolysis.

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.

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. ... Note, however, that the electron transport chain of prokaryotes may not require oxygen as some live in anaerobic conditions.

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.

It is also found in the thylakoid membrane of the chloroplast in photosynthetic eukaryotes. In bacteria, the electron transport chain is located in their cell membrane. In chloroplasts, light drives the conversion of water to oxygen and NADP+ to NADPH with transfer of H+ ions across chloroplast membranes.

An electron carrier is a molecule that transports electrons during cellular respiration. ... The energy stored in NADH + H+ and FADH2 will be released later in cellular respiration to generate ATP, which can be used as an energy source throughout the cell.

The electron transport chain and ATP synthase are embedded in the inner mitochondrial membrane. NADH and FADH2 made in the citric acid cycle (in the mitochondrial matrix) deposit their electrons into the electron transport chain at complexes I and II, respectively.

Electron transport chain (ETC) Inside the mitochondria of animal or plant cells, a series of chemical reactions produce ATP. This ATP contains chemical energy, and is the main "fuel" that cells use to stay alive.

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.

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.
