Facilitated Diffusion:Facilitated diffusion is a type of passive transport where specific transmembrane proteins assist in transporting larger or charged molecules across the cell membrane along their concentration gradient.
Equilibrium: Equilibrium refers to a state where there is no net movement of particles because concentrations are equal on both sides of a barrier. In diffusion, equilibrium occurs when there is no overall change in concentration over time.
Channel Proteins:These integral membrane proteins form channels across the cell membrane allowing for selective passage of specific ions or molecules based on size, shape, or charge.
