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.
