Biochemistry/Electron Transport Chain ETS in respiration In respiration, an electron transport chain is used to break the fall of electrons to oxygen into several energy-releasing steps. It slows down the releasing process of energy. There are a number of molecules that consists an electron transport chain.Most of these molecules are proteins, built into the inner membrane of mitochondria of eukaryotic cells and the plasma membrane of aerobically respiring prokaryotes.here are a number of molecules that consists an electron transport chain.

Electron transport chain The final acceptor of electrons in the electron transport chain is molecular oxygen. Electron transport chains are used for extracting energy via redox reactions from sunlight in photosynthesis or, such as in the case of the oxidation of sugars, cellular respiration.n oxidative phosphorylation, electrons are transferred from a low-energy electron donor (e.g., NADH) to an acceptor (e.g., O 2) through an electron transport chain. In photophosphorylation, the energy of sunlight is used to create a high-energy electron donor and an electron acceptor.

The Protein Complexes of the Electron Transport Chain The Protein Complexes of the Electron Transport Chain. Many years of effort have been devoted to the study of the remarkable processes in the mitochondria. The electron transport chain is the final stage of aerobic respiration leading to the forming of ATP in the inner membrane of the mitochondrion. The emergent picture is that of coupled reactions through five protein structures associated with that inner membrane.

The high energy electrons that enter the electron t t Electron Transport Chain Oxygen is the final acceptor of electrons from the electron transport chain. Oxygen receives the energy-spent electrons from the last of the carriers (i.e., cytochrome oxidase). After receiving electrons, oxygen combines with hydrogen ions, and water forms:

Passive transport Passive transport. Passive diffusion across a cell membrane. Passive transport is a movement of ions and other atomic or molecular substances across cell membranes without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

Electron transport chain In eukaryotes, an important electron transport chain is found in the inner mitochondrial membrane where it serves as the site of oxidative phosphorylation through the use of ATP synthase. It is also found in the thylakoid membrane of the chloroplast in photosynthetic eukaryotes.
