a cell membrane transport mechanism that transports two molecules at once through the membrane in opposite directions. See also countertransport and symport. Antiport: sodium-calcium exchanger. The electrochemical gradient of Na + is used to pump Ca 2+ out of the cell and thereby regulate the cytosolic Ca 2+ level. cell membrane transport mechanism that transports two molecules at once through the membrane in opposite directions.
