Molecular transport refers to the movement of molecules across biological membranes or within cells. This process is essential for various cellular functions, such as nutrient uptake, waste removal, signal transduction, and cellular communication. Researchers studying molecular transport investigate the mechanisms by which molecules are transported across membranes, as well as the factors that regulate and control this process. Understanding molecular transport is crucial for the development of new drugs and therapies targeting specific transport mechanisms, as well as for advancing our knowledge of cellular biology and physiology.
