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.

electron transport

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

1. 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.

Word History and Origins

Origin of electron transport¹

First recorded in 1950–55

Example Sentences

Previous research suggests that improving both the flow of ions across the RED membrane and the efficiency of electron transport would likely increase the amount of electricity captured from osmotic energy.

From Science Daily

Their novel approach uses light to control the electronic properties of the devices and opens the door to broader use of metal-metal contacts that could facilitate electron transport across the single-molecule device.

From Science Daily

Electron transport -- i.e. electric current -- also depends on the combination of molecular handedness and magnetization of the surface.

From Science Daily

Samples then made their way across campus and the country for additional analyses, including to Pasupathy's lab at Brookhaven National Laboratory for photoemission spectroscopy; to Philip Kim's lab at Harvard for electron transport measurements; and to the National High Magnetic Field Laboratory in Florida to study its magnetic properties.

From Science Daily

The results show that when you only take electron transport into account, the ratio of electronic conductivity to thermal conductivity approaches what the Wiedemann-Franz law predicts, Wang said.
