Question

. Can the polar molecules move across the plasma membrane? If not, then how are these
transported across the membrane?​

Answer 1

Answer:

Movement of polar molecules across the cell membrane –

1) The cell membrane is made up of a phospholipid bilayer and proteins.

2)The movement of polar molecules across the non-polar lipid bilayer requires carrier-proteins. ... As a result, they facilitate the transport of molecules across the membrane.
