Facilitated Diffusion:: Understanding the Process
Facilitated diffusion is an important biological process whereby molecules move across cell membranes with the help of transport proteins. Unlike simple diffusion, facilitated diffusion allows polar and charged molecules to traverse the membrane efficiently. Through specific protein channels or carriers, substances such as glucose, ions, and amino acids can passively move down their concentration gradients, ensuring essential nutrients enter cells while maintaining cellular equilibrium.
