In bacterial systems transport activities are performed by membraneproteins.
在细菌系统中运输活性是通过膜蛋白实现的。
2
Passive transport by facilitated diffusion requires the presence of specific integral membraneproteins to facilitate the movement of the molecule across the membrane.
协助扩散的被动运输则要求特定的内在膜蛋白去帮助分子完成跨膜运动。

To actively transport many of its proteins to extracytoplasmic compartments such as the periplasm and outer membrane, E.
