The Critical Role of Cell Membranes in Cell Function - postfix

Cell membranes are the outermost layer of cells, responsible for controlling the movement of substances in and out of the cell. They are composed of a phospholipid bilayer, with embedded proteins and lipids that facilitate various cellular functions. The cell membrane plays a critical role in maintaining cell homeostasis, regulating signaling pathways, and facilitating cell-cell interactions. In simple terms, the cell membrane acts as a gatekeeper, allowing certain substances to pass through while keeping others out.
