electron transport

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 ultimately being passed to molecular oxygen. The oxidation-reduction reactions generate the energy required for the production of ATP.

electron transport

n

(Life Sciences & Allied Applications / 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

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.
