cotransport
noun
co·trans·port
(ˌ)kō-tran(t)s-ˈpȯrt 
-ˈtran(t)s-ˌpȯrt
: the coupled transport of chemical substances across a cell membrane in which the energy required to move a substance (such as glucose) against a gradient in concentration or in electrical potential is provided by the movement of another substance (such as a sodium ion) along its gradient in concentration or in electric potential
The sodium-linked glucose transporters are largely restricted to the intestine and kidney, where they actively transport glucose against a glucose-concentration gradient by using sodium cotransport as an energy source.—
