Can small hydrophobic molecules cross the cell membrane?
Yes, small hydrophobic molecules can cross the cell membrane.
Can nonpolar molecules cross the cell membrane?
Yes, nonpolar molecules can cross the cell membrane through simple diffusion.
Can polar molecules cross the cell membrane?
Yes, polar molecules can cross the cell membrane through facilitated diffusion or active transport.
What feature of membrane describes whether molecules can cross the membrane?
permeabiity
Which molecule of a membrane describes whether molecules can cross the membrane?
permeability
Which feature of a membrane describes molecules whether can cross the membrane?
permeability
What is most likely to occur if the sugar molecules cross the membrane?
Sugar molecules move outside of the membrane.
The side from which more water molecules cross the semipermeable membrane?
The pure solvent side is the side from which more water molecules cross the semipermeable membrane.
Why can hydrophobic molecules cross the membrane?
Hydrophobic molecules can cross the cell membrane because the membrane is made up of a double layer of lipids, which are also hydrophobic. This allows hydrophobic molecules to pass through the membrane easily, while hydrophilic molecules have a harder time crossing.
Can small polar molecules cross the cell membrane?
Yes, small polar molecules can cross the cell membrane through a process called passive diffusion.

How easy or hard is it for polar molecules to pass through the cell membrane?
Polar molecules are effectively charged molecules. It's hard for them to cross the cell membrane because the membrane is comprised of an uncharged phospholipid bilayer. Charged molecules tend to have specific protein channels that allow them to cross the membrane.
