electron transport


Also found in: Medical, Wikipedia.

electron transport

n.
The movement of electrons from one electron carrier to another in a series of oxidation-reduction reactions. Electron transport is used in the light reactions of photosynthesis and in the final stage of cellular respiration to produce ATP from ADP, phosphate, and the energy that is released as an electron is moved from one carrier to another with a lower level of energy.

electron transport

n
(Biochemistry) biochem the metabolic process in mitochondria or chloroplasts, in which electrons are transferred in stages from energy-rich compounds to molecular oxygen with liberation of energy

elec′tron trans`port


n.
the stepwise transfer of electrons from one carrier molecule, as a flavoprotein or a cytochrome, to another and ultimately to oxygen during the aerobic production of ATP.

In addition, these changes may divert electrons to mitochondrial electron transport chain to form superoxides or ROS.
The parameters of pulse-amplitude modulation (PAM), that is, electron transport rate (ETR), were calculated using the WinControl software [25].
However, the conversion efficiency of nanoporous Ti[O.sub.2]-based DSSCs had stuck at around 11-12% due to the restricted electron extraction efficiency that resulted from slow electron transport mechanism and charge-carrier recombination by grain boundaries [4].
This electron transport chain is called a "Z-scheme" because the pattern of movement resembles the letter Z on its side.

The topics include the nitrogen cycle in the Archaean as an intricate interplay of enzymatic and abiotic reactions, the organization of respiratory electron transport chains in nitrate-reducing and nitrifying bacteria, the transport and assimilation of inorganic nitrogen in bacteria, the assembly of respiratory proteins of the nitrogen cycle, the physiology and regulatory mechanisms of nitric oxide metabolism, and nitrous oxide production in the terrestrial environment.
Eight chapters discuss frontiers in device engineering, atoms-up design, electron devices and electron transport, aperiodic dielectric design, design and the classical-quantum boundary, robust optimization in high dimensions, mathematical framework for optimal design, and future directions.
So I wouldn't be surprised if things like tooth decay or bone decay or dissolution of metals and minerals are all connected with this, specifically with what we call extracellular electron transport: the ability of these bugs to communicate electrically with the environment in ways that nobody taught us when we were students.
The electron transport chain is the major workhorse for creating ATP in living organisms, and yet there are very few ways to clearly illustrate the electron transport chain in the laboratory.
In the present investigation, we have evaluated mitochondrial LPO, 8-oxo-dG, oxidized glutathione, reduced glutathione, ATP, lipoic acid, TCA cycle enzymes and electron transport chain (ETC) complex activities in the brain of young versus aged rats.
