2020年4月25日 · Passive transport, also known as passive diffusion, is a process by which an ion or molecule passes through a cell wall via a concentration gradient, or from an area of high concentration to an area of low concentration.

Passive diffusion across a cell membrane. Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes. [1] [2] Instead of using cellular energy, like active transport, [3] passive transport relies on the second law of thermodynamics to drive the movement of substances across cell ...

被动运输（英文：Passive transport）指的是生物化学物质的运动或其他原子或分子穿过细胞膜。 不像 主动运输 ，该过程不需要 化学能 ，这是因为顺浓度梯度的跨膜转运总是伴随着系统 熵 增大的方向进行的。

被动运输(passive transport)是物质顺浓度梯度且不消耗细胞代谢能(ATP)所进行的运输方式，运输动力来自质膜内、外侧物质的浓度梯度势能或电位差。 被动运输分为简单扩散和易化扩散。

Passive transport is the fundamental movement of ions and other molecular substances within the cells along the concentration gradient, without any external energy. It is also known as passive d iffusion.

2022年6月16日 · Passive transport is a type of cellular transport in which substances such as ions and molecules move down their respective concentration gradients. It means that the substance tends to move from an area of higher concentration to an area of lower concentration.

2024年4月30日 · In this article, we will study the definition of passive transport, types of passive transport, diagram, of passive transport, examples of passive transport, the difference between active transport and passive transport, and the importance of active transport.

5 天之前 · In passive transport, substances move from an area of higher concentration to an area of lower concentration. A physical space in which there is a single substance concentration range has a concentration gradient. Selective Permeability.

2024年4月7日 · Passive transport, also known as passive diffusion, is the passage of an ion or molecule through a cell wall along a concentration gradient, or from a region of high concentration to a region of low concentration.

5 天之前 · Passive transport is the movement of substances across a cell membrane. It does not require cellular energy (ATP). The substances move from an area of high concentration to low concentration. This process is essential for maintaining homeostasis in cells. Passive transport helps cells absorb nutrients and expel waste.
