Polar molecules diffuse slowly to the cell membrane in if at alland non-polar diffuse rapidly…Why?

Answer 1

what the heck are you trying to say? you might want to re-ask this one. or explain what you mean.

Answer 2

Recall that, except for the relatively thin layer of polar head groups, the plasma membrane is mostly nonpolar (hydrophobic). Just as water cannot dissolve in oil, polar molecules are not soluble in the thick, nonpolar core of the membrane. Fatty, nonpolar molecules can, however, and so they are able to enter and exit the cell quite quickly by simple diffusion.

Answer 3

polar molecules are more water soluble, but the non-polar dissolves in the non-polar outer membrane.

If the molecules cannot get concentrated in the outer membrane, then it does not have as many opportunities to randomly diffuse to the inside of the cell.

Answer 4

Polar molecules may get caught by electrostatic attraction
- you know - like a magnet.
