Simple diffusion和facilitated diffusion有哪些异同点?相关知识点: 试题来源: 解析 单纯扩散和易化扩散的异同点: 都是将较小的分子和离子顺浓度差(不需要另外供能)的跨膜转运。单纯扩散与易化扩散的不同点:①单纯扩散的物质是脂溶性的,易化扩散的物质是非脂溶性的;②单纯扩散遵循物理学规律,例如扩散速度除与浓度差...
简单扩散(simple diffusion):无膜载体参与;不消耗能;运输速率与膜两侧浓度成正比,还与他们在水相与油相中的分配系数、电离度、分子大小等因素有关。(疏水的小分子与不带电荷的小极性分子) 协助扩散(facilitated diffusion):转运蛋白介导的,顺梯度转运的过程。 特点: 不消耗能 依被运输物质顺着浓度...
Step-by-Step Text Solution:1. Understanding Passive Transport: Both simple diffusion and facilitated diffusion are types of passive transport. This means that they do not require energy (ATP) to occur.2.
Types of Diffusion Diffusion across the cell membrane is either simple or facilitated. Simple diffusion Facilitated diffusion Mechanism Molecules move directly across the membrane without the aid of a carrier protein Movement occurs passively down a concentration gradient, however, the molecules require the...
