electron transport

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.

An example of this is coenzyme Q10, which is a key component in the oxidative phosphorylation section of energy production and electron transport chain as well as other organelle oxido-reductase activity.
Most of the potential energy received is diffused through the conversion to heat, while some of the potential energy cascade down through a electron transport chain, which ends up with the production of NADPH.
The two major activities within the mitochondrial are the Krebs' Cycle and the Electron Transport Chain.
The results of the detailed calculations on the electron states of silicon nanowires, comprised of 10,000 to 40,000 atoms, determined that electron transport characteristics will change depending on the cross-sectional shape of the nanowire.
Mitochondria have become the key source of energy within our bodies; they are, after all, where oxidative phosphorylation takes place in the electron transport chains, allowing us to make ATP molecules from glucose.
Following the electron transport chain, H+ travels across the membrane, forming a proton gradient.

It is clear that perezone acts as an electron sink which results in inhibition of electron transport (Carabez and Sandoval, 1988), but its cytotoxic activity has not been evaluated yet in the view of its possible use as anti-neoplasic agent.
The worms are paralysed by this form of the dye, we think, because it interferes with some electron transport system that controls movement.
Measurements of Chl fluorescence, both at physiological and low temperatures, have provided critical information on almost every aspect of the light energy absorption and conversion process that occurs in photosynthesis, with special relevance to our understanding of excitation energy migration within the antennae and to the cognate reaction centers, the energetic connectivity between antennas and reaction centers, the primary photochemistry and the secondary electron transport associated with the primary reactions.
