Gases diffuse most efficiently across what?
Diffusion of gases easily occurs across a membrane. The gases will have to be converted into liquids so as to diffuse easily.
What is an example for selectively premeable?
The phospholipid bilayer that composes the cell membrane is an example of a selectively permeable membrane. It only lets through small, non-polar molecules.
Why do oxygen molecules easily diffuse across a cell membrane while glucose molecules do not?
Oxygen molecules are small and nonpolar, which allows them to easily pass through the hydrophobic lipid bilayer of the cell membrane via simple diffusion. Glucose molecules, on the other hand, are larger and polar, making it more difficult for them to move through the nonpolar interior of the lipid bilayer. They require specific transport proteins or channels to facilitate their movement across the membrane.
What type of compound would easily diffuse into the cell?
A hydrophobic molecules (such as a steroid molecule) can easily diffuse into the cell
What substances easily diffuse a class of cell membrane?
sperm
What molecule is able to easily diffuse across the cell's membrane?
Carbon dioxide, oxygen and some nonpolar molecules diffuse easily.
Why do molecules easily diffuse across a cell membrane while glucose molecules do not?
Glucose is too big to pass throught.
What are 2 substances that diffuse freely across a cell membrane?
CO2, H2O, and O2 can all diffuse across a cell membrane. Also, small polar molecules (uncharged) and hydrocarbons easily diffuse across.
Gases diffuse most efficiently across what?
Diffusion of gases easily occurs across a membrane. The gases will have to be converted into liquids so as to diffuse easily.
Why do oxygen molecules easily diffuse across a cell membrane while protein molecules do not?
Cell membrane is semipermeable and oxygen molecules have size required for easy passqge while Glucose molecules do not have that size required for easy passage.

What molecules would easily be able to diffuse through a cell membrane without the help of a transport protein?
Water, any small molecule and lipids.
What type of compound would easily diffuse into the cell?
A hydrophobic molecules (such as a steroid molecule) can easily diffuse into the cell
Which particles can diffuse easily througn a cell membrane?
Oxygen
What substances easily diffuse a class of cell membrane?
sperm
Why cant polar molecules and ions diffuse across the cell membrane?
Ions cannot diffuse through a phospholipid bilayer because they are not able to dissolve in lipids, hence the phosphoLIPID bilayer . Also, since they have an electrical charge, they are repelled by the membrane.
