Facilitated diffusion water

WebFacilitated diffusion is diffusion that is helped along (facilitated by) a membrane transport channel. These channels are glycoproteins (proteins with carbohydrates attached) that allow molecules to pass through the membrane. WebJan 17, 2024 · Facilitated diffusion uses integral membrane proteins to move polar or charged substances across the hydrophobic regions of the membrane. Channel proteins can aid in the facilitated diffusion of substances by forming a hydrophilic passage through the plasma membrane through which polar and charged substances can pass.
