Answer :
the basic structure of biological membranes is provided by the lipid bilayer, membrane proteins perform most of the specific functions of membranes.
Lipid bilayers provide the fundamental structure of biological membranes, and membrane proteins carry out the majority of their particular tasks. Therefore, each type of cell membrane has certain functional characteristics that are provided by the proteins. As a result, a membrane has a wide range of protein kinds and quantities. Less than 25% of the membrane mass of the myelin membrane, which primarily acts as electrical insulation for nerve cell axons, is made up of protein. However, the interior membranes of mitochondria and chloroplasts, which are involved in ATP synthesis, contain about 75% protein. A typical plasma membrane falls halfway in the middle, with roughly 50% of its mass made up of proteins.
