What is cotransport nedir?

Cotransport, also known as secondary active transport, is a biological process whereby ions or molecules are transported across a biological membrane from an area of low concentration to an area of high concentration, against the concentration gradient. This is accomplished by coupling the energy released by the movement of one molecule or ion from high to low concentration with the movement of another molecule or ion from low to high concentration. This coupling occurs through the use of transport proteins that bind both molecules or ions and undergo changes in conformation to bring them across the membrane. Cotransport is an important process in many physiological functions, including the absorption of nutrients from the gut, the reabsorption of water and solutes from the kidneys, and the generation of electrical signals in nerve and muscle cells.
