Receptors for polar molecules are found ____, while receptors for nonpolar molecules are located ____.
A) on the cell surface; within the cell
B) within the cell; on the cell surface
C) on the cell surface; on the nuclear membrane
D) on the nuclear membrane; on the cell surface
E) on the cell surface; within the lipid bilayer

Question

Quizplus · Accepted Answer

Receptors for polar molecules are typically found on the cell surface because polar molecules cannot easily cross the lipid bilayer of the cell membrane. In contrast, receptors for nonpolar molecules are often located within the cell, as nonpolar molecules can diffuse through the lipid bilayer and interact with receptors inside the cell.
