How do solutes move along their concentration?

Solutes move along their concentration gradient through a process known as diffusion, where they naturally spread from areas of higher concentration to areas of lower concentration. This movement occurs until equilibrium is reached, meaning the concentration of solutes is uniform throughout the space. Additionally, in biological systems, solute transport can also occur via facilitated diffusion and active transport, which involve specific proteins or energy to help move solutes against their concentration gradient.
