Answeryes they do!, i just learned that in science great hah? Answer (improved)While proteins are a part of what makes up membranes, they are also made up of substances known as phospholipids.

Proteins build up cells and control their chemical reactions by means of enzymes which is a natural catalyst.

Actually the main skeleton of cell membrane is phospholipid, and proteins either float in the bilayer of phospholipid or attach to the outer layer of the membrane. Protein floats in the bilayer are usually carrier proteins and protein channels. Withe the help of Carrier proteins, cells can actively transport large particles into the cell(facilitated diffusion or active transport). Protein channels are for ions. The proteins that attached to the surface of the membrane are usually glycoproteins. They work as the signal acceptor to recognize signals such as hormones and toxins.
