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.
Can small polar molecules cross the cell membrane?
Yes, small polar molecules can cross the cell membrane through a process called passive diffusion.
Can CO2 diffuse through the lipid bilayer?
Yes, carbon dioxide (CO2) can diffuse through the lipid bilayer of a 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.
What ions are positively charged and can cross back and forth across neuron and cell membrane?
There are two ions that can cross the cell membrane. The positively charged sodium and potassium ions can cross back and forth across the neuron cell membrane.
What Lipid do in cell membrane?

Can polar molecules cross the cell membrane?
Yes, polar molecules can cross the cell membrane through facilitated diffusion or active transport.
What does the plant cell membrane let through?
Water, oxygen, co2
Whats the nuclear membrane?
# The nuclear membrane is a thin membrane covering an animal cell. It holds in the cytoplasm, which in turn contains the organelles and nucleus of the cell. The cell membrane also allows the exchange of nutrients and oxygen/CO2.
Can small polar molecules cross the cell membrane?
Yes, small polar molecules can cross the cell membrane through a process called passive diffusion.
What is cell membrane permeability?
It is the ability of the membrane to allow ions and/or particles to cross.
What receptor has a ligand that can cross the cell membrane that binds?
Intracellular
What are two structures that a material would have to cross to enter the cytoplasm of a plant cell?
In order to enter the cytoplasm of a plant cell, a material would have to cross the plasma membrane and then the cell wall. The plasma membrane regulates what enters and exits the cell, while the cell wall provides structural support and protection.
What is the process where in the diffusion of water cross a cell membrane?
Osmosis
