one area of the plate and rely on them to diffuse throughout the gel, moving away from the area where they are highly concentrated. Likewise, osmosis can play a role in scientific experiments where people need to move water across a membrane by changing the balance of salts on either side...

This refers to the movement of a permeant across a membrane from a region of high concentration to that of low concentration by a process of diffusion. The rate of passive transport is proportional to the concentration gradient of the permeant across the membrane. P eff (Effective intestinal ...

In osmosis, why does the solute not cross over the membrane? What is movement of cell against concentration gradient is called A. osmosis B. active transport C. diffusion D. passive transport Describe the difference between active and passive transport across the membrane....
Passive diffusion refers to the process where lipophilic uncharged molecules move across a membrane by dissolving in the lipid layer, driven by a concentration gradient without the need for energy expenditure by the cell. AI generated definition based on: Encyclopedia of Toxicology (Second Edition),...
