Lipid-Soluble Materials Enter and Exit the Cell Via

Question

Lipid-soluble materials enter and exit the cell via:
A) osmosis across a carrier protein.
B) diffusion across the cell membrane.
C) diffusion through a transport protein.
D) active transport.

Accepted Answer

Lipid-soluble materials can diffuse directly across the cell membrane because they can easily pass through the lipid bilayer without the need for transport proteins or energy input.
