2023年10月31日 — Diffusion is a process of passive transport in which molecules move from an area of higher concentration to one of lower concentration.

The simplest plasma membrane transport mechanism is called passive diffusion. It is the movement of ions and other molecules within the cells along the ...

The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration, and/or osmosis. Passive diffusion across a cell membrane.

In passive transport, substances move from an area of higher concentration to an area of lower concentration in a process called diffusion. A physical space in ...

Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.

Simple diffusion is the movement of molecules through a cell membrane without using the channels formed by integral membrane protein. Facilitated diffusion is ...

Passive diffusion is the predominant mechanism for the permeation of drugs throughout the body. A compound must have favorable physicochemical properties (i.e., ...

2019年8月20日 — Passive transport is the diffusion of substances across a membrane. This is a spontaneous process and cellular energy is not expended. Molecules ...
