膜运输蛋白(membrane transport protein) 膜运输蛋白(membrane transport protein) 也叫膜转运蛋白。能选择性地使非自由扩散的小分子物质透过质膜。 细胞膜是脂双分子层、蛋白质和少量糖组成的,就其化学本质而言,是半透膜。用人工脂膜测定证实,脂溶性分子和不带电的极性小分子易于通过质膜扩散,例如O2、N2、乙醇、尿素...

passive transport of molecules through a membrane, without the need of protein channels (oxygen diffusion) 扩散是一种物理现象(Molecules are always moving, even when they are equally distributed/ have reached equilibrium),放到生物中物质进出细胞膜则发生于这种物质可以随意进出细胞的时候,比如一些非极性分子...
膜运输蛋白(membrane transport protein) 膜运输蛋白是膜整合蛋白, 或是大的跨膜分子复合物, 功能是参与被动运输(促进扩散)或主动运输(运输泵)。参与促进扩散的膜运输蛋白虽然没有酶活性, 但是具有酶催化的特点,如可达到最高速率、具有特异性和竞争抑制等,因此,运输蛋白又被称为透性酶(permease)。
也称膜运输蛋白。能选择性地使非自由扩散的小分子物质透过质膜。

Membrane transport proteins, together with other proteins, represent about 50% of the mass of fungal cell membranes (Gooday, 1994), and so these transporters could represent a notable investment of N. Thus, production of a given membrane transporter protein may be evolutionary advantageous only ...
