Ion channels and ion pumps

Web1 mrt. 2015 · An ion channel is simply a membrane protein that forms an ion-friendly passageway through the membrane, so that the ions can get through in the direction they want to go. A pump is different. It actually grabs ions and pushes them through the membrane in a certain direction, whether they want to go that way or not. WebIon channels provide a conductance pathway for the passive transport of ions across membranes. These functional molecules perform key tasks in biological systems such as neuronal signaling, muscular control, and sensing. Recently, function-oriented synthesis researchers began to focus on ion channels with the goal of modifying the function of …
