Examples of Facilitated Diffusion
Some Example of Facilitated Diffusion are given below:
- Glucose Transport: Glucose transporter proteins facilitate the diffusion of glucose molecules across cell membranes, ensuring cells have access to this vital energy source.
- Ion Channels: Ion channel proteins allow the facilitated diffusion of ions such as sodium (Na⁺), potassium (K⁺), and chloride (Cl⁻) across cell membranes, maintaining cellular ion balance.
- Amino Acid Transport: Transporter proteins facilitate the diffusion of amino acids into cells, supporting protein synthesis and cellular metabolism.
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.
