| electron spin resonance spectroscopy | <radiology> A technique applicable to the wide variety of substances which exhibit paramagnetism because of the magnetic moments of unpaired electrons. The spectra are useful for detection and identification, for determination of electron structure, for study of interactions between molecules, and for measurement of nuclear spins and moments. electron nuclear double resonance (endor) spectroscopy is a variant of the technique which can give enhanced resolution. Electron spin resonance analysis can now be used in vivo, including imaging applications. (12 Dec 1998) |

| electron trajectory | <physics> The path of an electron. (05 Aug 1998) |
| electron transfer flavin | <biochemistry> Flavoproteins that participate in the electron transport pathway. (05 Mar 2000) |
| electron-transferring flavoprotein dehydrogenase | <enzyme> System formed of electron-transferring flavoproteins plus EC 1.3.99.2 or EC 1.3.99.3 (butyryl-CoA dehydrogenase or acyl-CoA dehydrogenase) which reduces ubiquinone and other acceptors Registry number: EC 1.- Synonym: etf dehydrogenase, electron transfer flavoprotein-q oxidoreductases, electron transfer flavoprotein-ubiquinone oxidoreductase, etf-uo (26 Jun 1999) |
| electron transport | The transport of electrons through a number of electron carriers in a set sequence. (09 Oct 1997) |
| electron transport chain | <biochemistry, chemistry> A series of compounds that transfer electrons to an eventual donor with concomitant energy conversion. One of the best studied is in the mitochondrial inner membrane, that takes NADH (from the tricarboxylic acid cycle) or FADH and transfers electrons via ubiquinone, cytochromes and various other compounds, to oxygen. Other electron transport chains are involved in photosynthesis. (18 Nov 1997) |
| electron transport particles | <cell biology> Fragments of mitochondria still capable of transporting electrons. One of the units occurring on the matrical surface of mitochondrial cristae; the head of the particle which measures about 9 nm, attaches to the membrane of the crista by a stalk 5 nm in length; the particle may be concerned with the electron transport system. Synonym: submitochondrial particles. (05 Mar 2000) |
| electron transport phosphorylation | <biochemistry> Synthesis of ATP involving a membrane associated electron transport chain and the creation of a proton-motive force. (09 Oct 1997) |
| electron transport system | The mitochondrial electron transport chain. (18 Nov 1997) |
| electron velocity | <physics> The rate of motion of an electron. (05 Aug 1998) |
| electron-volt | <unit> A general unit of energy of moving particles, equal to the kinetic energy acquired by an electron losing one volt of potential, equal to 1.602 x 10-19 J. This is the energy an electron (or other particle of charge=1 such as a proton), gains as it is accelerated through a potential difference of 1 volt. In plasma physics the electron-volt is used as a unit of temperature when the mean particle energy is 1 eV, the temperature of the plasma is roughly 11, 600 Kelvin (the conversion from eV to K is via the Boltzmann constant). Abbreviation: eV (09 Oct 1997) |
| electron wavelength | <physics> The wavelength necessary to account for the deviation of electron rays in crystals by wave diffraction theory. It is numerically equal to the quotient of Planck's constant divided by the electron momentum, mv. = h / mv, where: h = Planck's constant m = mass of electron v = velocity of electron (05 Aug 1998) |
| emission electron | <physics>? A beta particle resulting from radioactive decay. (05 Mar 2000) |
| transition electron | An electron that moves from one energy level to another to fill a vacancy in a shell, with the emission of characteristic radiation. (05 Mar 2000) |
| transmission electron microscopy | <technique> Those forms of electron microscopy in which electrons are transmitted through the object to be imaged, suffering energy loss by diffraction and to a small extent by absorption. Acronym: TEM (18 Nov 1997) |
