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.

—Peter R. Shepherd and Barbara B. Kahn
