glucose transporters

Glucose transporters are specialized proteins located in cell membranes that facilitate the movement of glucose, a primary energy source, from the bloodstream into cells. They function like gatekeepers, recognizing glucose molecules and enabling their entry through a process called facilitated diffusion, which doesn't require energy. Different types of glucose transporters are found in various tissues—such as muscles and the brain—each adapted for specific roles and glucose levels. These transporters are essential for providing cells with the fuel needed for activities like energy production and metabolic functions.
