Cotransporters are transmembrane proteins that facilitate the movement of molecules in the same direction (symporters) or in opposite directions (antiporters).
Cotransporters are proteins that couple the movement of a solute against its concentration gradient, driven by the movement of another solute down an electrochemical gradient, in one direction.
Therefore, we can conclude that cotransporters move a molecule into a cell against a concentration gradient in one direction.
