| Embden-Meyerhof-Parnas pathway | A pathway that degrades glucose to pyruvate, the six-carbon stage converts glucose to fructose-1,6-bisphosphate, and the three-carbon stage produces ATP while changing glyceraldehyde-3-phosphate to pyruvate. Compare: Entner-Doudoroff pathway. (09 Oct 1997) |
|---|---|
| Embden-Meyerhof pathway | The main pathway for anerobic degradation of carbohydrate. Starch or glycogen is hydrolysed to glucose 1 phosphate and then through a series of intermediates, yielding two ATP molecules per glucose and producing either pyruvate which feeds into the tricarboxylic acid cycle) or lactate. (18 Nov 1997) |
| Entner-Douderoff pathway | A degradative pathway for carbohydrates in certain microorganisms (e.g., Pseudomonas sp.) that lack hexokinase, phosphofructokinase, and glyceraldehyde-3-phosphate dehydrogenase. (05 Mar 2000) |
| Entner-Doudoroff pathway | <biochemistry> A pathway that converts glucose to pyruvate and glyceraldehyde-3 phosphate by producing 6-phosphogluconate and then dehydrating it. (09 Oct 1997) |
| extrinsic pathway | <haematology> Initiation of blood clotting as a result of factors released from damaged tissue, as opposed to contact with a foreign surface (the intrinsic pathway). Tissue thromboplastin (Factor III) in conjunction with Factor VII proconvertin) will activate Factor X that, once activated, converts prothrombin to thrombin. (27 Jun 1999) |
| 4-aminobutyrate pathway | The pathway that ultimately converts 4-aminobutyrate to succinate; succinate is then converted to alpha-ketoglutarate, via the tricarboxylic acid cycle, which is then acted upon by glutamate dehydrogenase; glutamate is then decarboxylated to reform 4-aminobutyrate; an important pathway for those cells which make this neuroactive molecule. Synonym: GABA pathway. (05 Mar 2000) |
| lysogenic pathway | <virology> The method by which a virus becomes a dormant, passive part of its host bacterium's genome (a lysogenic virus), choosing to insert its DNA into the host's and postponing completion of its lytic cycle, at which time it destroys the host and spreads its progeny to infect other bacterial cells (enters the lytic pathway). (09 Oct 1997) |
| lytic pathway | The steps in the method that a virus takes to complete a lytic cycle, including the production and assembly of progeny viruses with host cell machinery and the destruction of the host cell by rupturing its plasma membrane (lysis), releasing the progeny viruses in the process. (09 Oct 1997) |
| ambiguous atrioventricular connections | Connections in which half the atrioventricular junction is connected concordantly and the other half is discordantly connected. (05 Mar 2000) |
| anomalous atrioventricular excitation | Ectopic atrial beat conducted to the ventricle. (05 Mar 2000) |
| anterior cusp of atrioventricular valve | The anterior leaflet or valvule of either the tricuspid or mitral valves. Synonym: cuspis anterior valvae atrioventricularis dextrae/sinistrae. (05 Mar 2000) |
| artery to atrioventricular node | The atrioventricular branches or the nodal branches, the small arteries supplying the atrioventricular node; they usually arise from the right coronary artery where it starts to descend the posterior interventricular sulcus. Synonym: ramus nodi atrioventricularis, atrioventricular nodal branch, branch to atrioventricular node. (05 Mar 2000) |
| atrioventricular | <anatomy, cardiology> Pertaining to an atrium of the heart and to a ventricle. (16 Dec 1997) |
| atrioventricular band | The bundle of modified cardiac muscle fibres that begins at the atrioventricular node as the trunk of the atrioventricular bundle and passes through the right atrioventricular fibrous ring to the membranous part of the interventricular septum where the trunk divides into two branches, the right crus of the atrioventricular bundle and the left crus of the atrioventricular bundle; the two crura ramify in the subendocardium of their respective ventricles. Synonym: fasciculus atrioventricularis, atrioventricular band, Gaskell's bridge, His' band, His' bundle, bundle of His, Keith's bundle, Kent's bundle, Kent-His bundle, ventriculonector. (05 Mar 2000) |
| atrioventricular block | <cardiology> A conduction disturbance that results in the inappropriate delay (or complete inability) of a electrical impulse, generated in the atria, to reach the ventricles (via the atrioventricular node). Clinical types are divided into first (nonserious), second and third degree (most serious). Some drugs may precipitate atrioventricular block (for example clonidine, methyldopa, verapamil). A permanent pacemaker may be required for a third degree (complete) heart block. (02 Jan 1998) |
