Options

A. upper layer is non-polar and hydrophilic
B. upper layer is polar and hydrophobic
C. phospholipids form a bimolecular layer in middle part
D. proteins form a middle layer

Answer

C

Explanation

According to the fluid mosaic model, the cell membrane consists of a highly viscous fluid matrix of two layers of phospholipid molecules. Protein molecules (or their complexes) occur in membrane
but not in continuous layer.
