Example:
Imagine you're at a crowded concert trying to get to the VIP section, but the only way through is with the help of a security guard. This situation is similar to facilitated diffusion, where molecules move across a cell membrane with the assistance of transport proteins. Just as the security guard helps you navigate through the crowd to reach the exclusive area, transport proteins assist specific molecules in crossing the cell membrane, ensuring they get to their destination efficiently amidst the packed environment.

Facilitated Diffusion: The transport of materials across the cell membrane by transport proteins. Facilitated diffusion. Facilitated diffusion is a process where transport proteins help move substances across a cell membrane without using energy.
