(biochemistry)
The components of the final sequence of reactions in biological oxidations; composed of a series of oxidizing agents arranged in order of increasing strength and terminating in oxygen.

The function of mtGPDH has largely been discussed in mammals and invertebrates such as the fruit fly Drosophda melanogaster; the enzyme may act as part of the mitochondrial electron transport chain by transferring electrons to ubiquinone and acting as an uncoupling mechanism susceptible to proton leak (Miwa et al.
This is a complex multi-step process that occurs along the electron transport chain, which serves as a "power line" through which chemical energy is released and transferred into ATP.
Some medications can directly affect electron transport chain complexes or damage electron transport chain components.
Fluorescence changes during the fast part (between steps O and P) of the transient can be primarily correlated with the events taking place in the course of successive reduction of the electron acceptors of the entire photosynthetic electron transport chain.
The flux through the electron transport chain is relevant to the aging process because it is related to the rate of production of ROS.
As the presence of heavy metals inhibits the electron transport chain in photosynthesis, hence increases the fluorescence emission as an alternative channel to drain the energy collected from the sun.
Oxygen molecules are required for the removal of electrons from the electron transport chain in the mitochondria.
We do not fully understand the reasons behind these differences between the two photosystems, but they seem to be related to differences in the manner the antennas are coupled to the reaction centers, and also to characteristics and organization of the electron transport chain downhill of the charge separation at PSI.
They are passed downhill, releasing energy through a series of protein molecules that comprise an electron transport chain.
The mitochondrial electron transport chain (7) consists of five enzyme complexes.
The unique position of SDH on the matrix side of the inner mitochondrial membrane enables SDH to participate in both the Krebs cycle and the electron transport chain.
The electron transport chain is involved in mitochondrial energy production," says Johnson.
