Question

question 3
the primary structural components of the cell membrane are
○ phospholipids and proteins
○ cholesterol
○ cellulose
○ glycoproteins

Explanation:

The cell membrane follows the fluid mosaic model, where phospholipids form the fundamental bilayer structure. Proteins are embedded or associated with this bilayer, carrying out key structural and functional roles. Cholesterol is a minor component that modulates membrane fluidity, cellulose forms plant cell walls (not membranes), and glycoproteins are specialized protein components but not one of the two primary structural building blocks.

Answer:

phospholipids and proteins
