Ion Transport

Medical Definition:	The movement of ions across energy-transducing cell membranes. Transport can be active, passive or facilitated. Ions may travel by themselves (uniport), or as a group of two or more ions in the same (symport) or opposite (antiport) directions.
Guide Notes:	in biol systems: do not confuse with ION EXCHANGE, a physicochem process; coord NIM with endogenous substance /metab (IM) or with exogenous substance /pharmacokin (IM); if active transport, coord with BIOLOGICAL TRANSPORT, ACTIVE
Also Called:	Active Ion Transport,Antiport,Facilitated Ion Transport,Ion Exchange, Intracellular,Passive Ion Transport,Symport,Uniport
Previously Indexed:	Ion Exchange (1966-1992)
