Membrane Traffic

Membrane traffic refers to the process by which cells transport molecules, such as proteins and lipids, within different parts of the cell or in and out of the cell. This involves specialized structures called vesicles—tiny bubbles that bud off from one membrane and fuse with another—enabling precise delivery and removal of materials. This system maintains cellular organization, supports communication, and ensures that enzymes and other molecules reach their correct locations to sustain normal cell function. Essentially, membrane traffic is the cell’s internal shipping network, coordinating the movement of essential components efficiently and accurately.
