antiport

antiport

 [an´tĭ-port]
a cell membranetransport 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 Ca2+ out of the cell and thereby regulate the cytosolic Ca2+ level.

an·ti·port

(an'tē-pōrt),
The coupled transport of two different molecules or ions through a membrane in opposite directions by a common carrier mechanism (antiporter). Compare: symport, uniport.

Therefore, the antiport crosstalk between starch and cellulose biosyntheses [36, 37, 38] is mediated by Pi translocator and glucosyltransferase via the plus/plus strands sequence homology of the GDH-synthesized RNAs that regulate the abundance of their mRNAs.
This type of transport is called: (a) cotransport (b) antiport (c) symport (d) a and b (e) duoport Answer = d 3.
On the other hand, an increased rate of Na/Mg antiport in hemodialysis patients, which leads only to Mg efflux out of RBC, partially compensates for the intracellular increase [24].
