Question

Quizplus · Accepted Answer

Phospholipids are the main component of the cell membrane, forming a phospholipid bilayer that provides a selectively permeable barrier for the cell. Steroids can also contribute to membrane structure, but are not directly important for membrane function. Polysaccharides and DNA are not major components of the membrane. ATP is an energy molecule and not a structural component of the membrane.
