|---|---|---|---|
| 설명 | 원자에 정상보다 과다, 과소한 중성자나 양자를 가지고 있는 경우에 원자가 안정되기 위해서 붕괴가 생긴다. 이런 붕괴에는 다음과 같은 3가지 방법이 있다. 알파－붕괴는 알파입자를 방출하여 안정되는 법, 즉 원자번호는 2씩 감소하고 질량수는 4씩 감소한다. 알파입자란 알파붕괴에 의해서 생기는 헬륨의 핵과 같은 입자를 말한다. |

| 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) |

| reverse electron transport | <chemistry> The energy-dependent movement of electrons against the thermodynamic gradient to form a strong reductant from a weaker electron donor. (11 Jan 1998) |
|---|---|
| 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 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) |
| alpha particles | Positively charged particles composed of two protons and two neutrons, i.e., helium nuclei, emitted during disintegration of very heavy isotopes; a beam of alpha particles or an alpha ray has very strong ionizing power, but weak penetrability. (12 Dec 1998) |
| chromatin particles | Fine bluish dots thought to represent remnants of the nucleus, occasionally seen in stained erythrocytes. (05 Mar 2000) |
| submitochondrial particles | The various filaments, granules, tubules or other inclusions within mitochondria. (12 Dec 1998) |
| elementary particles | <radiobiology> at a nuclear-energy level: electron & positron - seem to be stable, proton - thought to be stable, life greater than 10^30 sec, neutron - decays in ?6 min unless its in a nucleus, which often extends its life. Other particles important for nuclear energy: Muon, neutrino (m, e, tau), photon, Muonic atoms, Pi-meson antiparticles (09 Oct 1997) |
| kappa particles | Inheritable cytoplasmic symbionts, once thought to be particle's mainly or exclusively of DNA, occurring in some strains of Paramecium; capable of producing a product lethal to other strains. (05 Mar 2000) |
| active transport | <biochemistry, chemistry> Transport of ions, nutrients or other molecules into a cell against a concentration gradient, this requires the expenditure of energy through ATP hydrolysis. (06 May 1997) |
| anterograde transport | Movement of material from the cell body of a neuron into axons and dendrites retrograde axoplasmic transport also occurs). (18 Nov 1997) |
| atrial transport function | The role of the atria in filling and stretching the ventricles by their presystolic contraction, without which the force of ventricular contraction and hence the cardiac output may significantly decrease. (05 Mar 2000) |
| axonal transport | Directed transport of organelles and molecules along a nerve cell axon. Transport can be anterograde (from the cell body) or retrograde (toward the cell body). (alberts et al., molecular biology of the cell, 3d ed, pg3) (12 Dec 1998) |
| axoplasmic transport | Transport by way of flow of axoplasm toward cell soma (retrograde) or toward axon terminal (anterograde). (05 Mar 2000) |
