Question

which diagram best represents the phospholipid structure of a cell membrane? a. cell membrane inside the cell outside the cell b. cell membrane inside the cell outside the cell c. cell membrane inside the cell outside the cell

Explanation:

The cell - membrane has a phospholipid bilayer structure. The hydrophilic heads of phospholipids face the aqueous environments (inside and outside the cell), and the hydrophobic tails face each other in the interior of the bilayer. In a correct representation, the heads should be on the outer and inner surfaces of the membrane, and the tails should be in the middle.

Answer:

A. The diagram in option A correctly shows the phospholipid bilayer with the hydrophilic heads facing the inside and outside of the cell and the hydrophobic tails in the middle.
