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 (this is a hydrogen ion H+ gradient), established via breakdown of ATP for energy, across the membrane-more acidic outside the cell than inside the cell. Phosphate transport may best described as an example of O cotransport or secondary active transport O facilitated diffusion O active transport O passive diffusion O osmosis
