Transmembrane proteins span the width of cell membranes. Four types of transmembrane proteins are shown in a section of cell membrane. Although these proteins have different specific functions, they all —

• stop chemical reactions within the cell

• synthesize molecules that signal other cells

• help the cell interact with its environment

• remove large waste particles from the cytoplasm of the cell
