Question

to which of the following is the plasma membrane the most freely permeable? multiple choice small nonpolar molecules large nonpolar molecules large neutral molecules small polar molecules

Explanation:

The plasma membrane is a lipid - bilayer. Small nonpolar molecules can easily pass through the hydrophobic interior of the lipid - bilayer without the need for transport proteins. Larger molecules and polar molecules have more difficulty passing through due to the hydrophobic nature of the membrane interior.

Answer:

A. Small nonpolar molecules
