Question

Quizplus · Accepted Answer

Phospholipids are the most abundant molecules in cell membranes, forming a bilayer that acts as a barrier between the cell and its environment. Proteins are also important components of cell membranes, but they are not as abundant as phospholipids. Sugars, fatty acids, and steroids are also present in cell membranes but in smaller quantities.
