Electron-transport
noun, Biochemistry.
1.
the stepwise transfer of electrons from one carrier molecule, as a flavoprotein or a cytochrome, to another along the respiratory chain and ultimately to oxygen during the aerobic production of ATP.
noun
1.
(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
electron transport n.
The successive passage of electrons from one cytochrome or flavoprotein to another by a series of oxidation-reduction reactions during the aerobic production of ATP, with the electrons originating from an oxidizable substrate and passing to molecular oxygen.
electron transport
The movement of electrons from one electron carrier to another in a series of oxidation-reduction reactions, with each electron transferred to a slightly lower level of energy, so that energy is released. Electron transport is used in the light reactions of photosynthesis and in the final stage of cellular respiration to produce ATP from ADP and phosphate.
