In cell biology, what is the primary structural component of the biological cell membrane described by the fluid mosaic model?
Answer and explanation
Correct answer: A. A phospholipid bilayer with embedded integral and peripheral proteins
- Step 1: Cell membranes consist of an amphipathic phospholipid bilayer with hydrophobic fatty acid tails inward and hydrophilic heads outward. Answer: A phospholipid bilayer with embedded integral and peripheral proteins. Why not the others: Cellulose forms plant cell walls, not plasma membranes.
