    Answer:

    active; prokaryotes

    Explanation:

    Active transport can be defined as the movement of molecules across cell membranes against a concentration gradient, i.e., from a region of low concentration to a region of high concentration. Group translocation is a specialized type of active transport observed in prokaryotic cells. In group translocation, the transported substance is chemically modified during its movement, thereby the cell membrane becomes impermeable to this substance once it is within the cell. In bacteria, the phosphotransferase system is a type of group translocation that uses phosphoenolpyruvate (PEP) as a source of energy to transport sugar molecules into the cell.
