Passive transport - Wikipedia
https://en.wikipedia.org/wiki/Passive_transport
WebPassive 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 membranes.

WebApr 25, 2020 · Basically, passive transport gives an ion or molecule “room to breathe.” 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.

WebThere are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.

WebJun 16, 2022 · In passive transport, substances (e.g. ion s and solute s) move across a membrane from a region of their higher concentration to a region of their lower concentration. The movement is described as downhill. Because of this, cellular energy (e.g. ATP) is not required as it is in active transport.
