Most cells have a membrane potential, which means that there is a potential difference between inside and outside. An electrochemical gradient is created by different material and charge distribution. Special formations in animal cell membranes are the microvilli, pseudopodia-like protuberances to the outside, which enlarge the surface of the membrane and together form the ″Bürstensaum″ of the cell. A cell membrane is the demarcation between different cells. In addition, an exchange of substances takes place in the cell membrane.
