| coupled transport | The linked, simultaneous transport of two substances across a cell membrane (or another intracellular membrane). If the two substances are moving in the same direction (both into the cell or both out of the cell) it is called symport. If the two substances are moving in opposite directions (one moves into the cell while the other moves out) it is called antiport. (09 Oct 1997) |

| G-protein coupled receptor | <cell biology> Cell surface receptors that are coupled to G-proteins (GTP-binding protein). G-protein coupled receptors are thought to have seven membrane spanning domains and have been divided into 2 subclasses: those in which the binding site is in the extracellular domain for example receptors for glycoprotein hormones, such as thyroid stimulating hormone (TSH) and follicle-stimulating hormone (FSH) and those in which the ligand binding site is likely to be in the plane of the 7 transmembrane domains for example rhodopsin and receptors for small neurotransmitters and hormones for example muscarinic acetylcholine receptor.

| coupled beats | Beats (usually premature) that recur at a fixed interval from a preceding (usually normal) beat. (05 Mar 2000) |
| coupled pulse | A pulse in which the beats occur in pairs. Synonym: bigemina, coupled pulse, pulsus bigeminus. (05 Mar 2000) |
| coupled reaction | Two chemical reactions that share a common intermediate (for example, the productof the first reaction is a reactant in the second) and therefore havesome kind of energy exchange between them. (09 Oct 1997) |
| coupled rhythm | That cardiac rhythm when each beat of the dominant rhythm (sinus or other) is followed by a premature beat, with the result that the heartbeats occur in pairs (bigeminy). Synonym: coupled rhythm. (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) |
| biological transport | The movement of materials (including biochemical substances and drugs) across cell membranes and epithelial layers, usually by passive diffusion. (12 Dec 1998) |
| biological transport, active | The movement of materials across cell membranes and epithelial layers against an electrochemical gradient, requiring the expenditure of metabolic energy. (12 Dec 1998) |
| vectorial transport | <physiology> Transport of an ion or molecule across an epithelium in a certain direction (e.g. absorption of glucose by the gut). Vectorial transport implies a nonuniform distribution of transport proteins on the plasma membranes of two faces of the epithelium. (06 Mar 2000) |
| paracellular transport | Solvent movement across an epithelial cell layer through the tight junctions between cells. Compare: transcellular transport. (05 Mar 2000) |
| vesicular transport | <cell biology> Process of transport of material across an epithelium by uptake on one face into a coated vesicle, which may then be sorted through the trans Golgi network and transported to the opposite face in another set of vesicles. (17 Mar 1998) |
