Question 10 (1 point) Regarding the movement of various substances across the plasma membrane, the hydrophobic lipid interior prevents free diffusion of ions, charged, and polar molecules many macromolecules protein transporters (transmembrane proteins) allow the import and export of some molecules that cannot get across on ther (e.g proteins, polysaccharides) are too large to cross the plasma membrane on their own own gases, lipids , and small uncharged polar molecules are blocked from aiffusing across the plasma membrane

Explanation / Answer

The answer is B. Many macromolecules are too large to cross the plasma membrane on their own.
