The phosphate transport system in bacteria imports phosphate into the cell even when the concentration of phosphate outside the cell is much lower than the cytoplasmic phosphate concentration. Phosphate import depends on a pH gradient across the membranemore acidic outside the cell than inside the cell. In this bacterial cell, phosphate transport is an example of ________.

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.
