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

Co-transport.

Explanation:

Co-transport may be defined as the process of transport of two molecules across the membrane without the use of energy. Two types of co transport are symport and antiport.

The bacteria transport system import phosphate into the cell. The import of the phosphate depends on pH. Since, the import of phosphate depends on pH and does not depend on the ATPase activity. Here, the phosphate molecules can simultaneously cross the membranes.

Thus, the answer is co-transport.

the organisms are not adapted to live in some communities or habitats.

im not in connections yet but i might can you some questions. what grade are you in?
