Answer:Cotransport
Explanation:Contransport is 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.
An example is the Na+/glucose cotransporter (SGLT), which couples the movement of Na+ into the cell down its electrochemical gradient to the movement of glucose into the cell against its concentration gradient. Cotransport is also commonly referred to as symport.
