The fluid mosaic model describes membranes as
A.a phospholipid bilayer with proteins drifting within it
B.a rigid lattice of proteins
C.a single layer of phospholipids
D.a carbohydrate-only sheet
Explanation
Core Concept
Phospholipids and proteins move laterally in the plane — 'fluid' — while the embedded proteins create the 'mosaic' pattern. This mobility supports transport and signaling.
Correct Answer
Aa phospholipid bilayer with proteins drifting within it
