Mediated transport, also known as facilitated transport, refers to the process by which substances move across a biological membrane with the assistance of specific proteins. This process is different from simple diffusion, where molecules pass through the membrane unaided, and it is essential for transporting substances that cannot cross the lipid bilayer of cell membranes easily due to size, charge, or polarity.
