ATP-driven Transport

Caption: In comparison to those in normal cells (top row), fluorescent proteins in ATP-depleted cells (bottom row) took much longer to diffuse from one side of a cell to another—the distance indicated by the red dotted line. According to the study in Cell, ATP-driven processes produce the fluctuating forces required for proper transport within the cytoplasm.
