Definitions for "Antiport"
A membrane transport process that carries one substance in one direction and another in the opposite direction. (Contrast with symport.)
Membrane carrier protein that transports two different ions or small molecules across a membrane in opposite directions, either simultaneously or in sequence.
Primary active transport creates a gradient for the movement of another substance in a secondary manner. Where the movement is opposite in direction to the primary change, it is antiport. See also secondary active transport, symport.
