What else can I help you with?
Name 3 particles that are small enough to diffuse freely across the cell membrane?
H2O CO2 O2 hope this helps
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.
Why can oxygen diffuse across a cell membrane but a protein?
Its too large
How do water-soluble molecules diffuse through the cell membrane?
Water-soluble molecules diffuse through the cell membrane by passing through protein channels or transporters that are embedded in the membrane. These channels and transporters allow the molecules to move across the membrane, from an area of high concentration to an area of low concentration, without requiring energy.
Occurs when water molecules diffuse through a membrane?
Osmosis. This is the movement of water molecules from an area of high water concentration to an area of low water concentration across a semi-permeable membrane.
What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.
How do you use diffuse in sentence?
Oxygen molecules diffuse across the membrane.

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 part of the lung do oxygen molecules diffuse across into the bloodstream?
Oxygen molecules diffuse across the alveolar membrane in the lungs into the bloodstream. This is where gas exchange occurs, with oxygen moving from the alveoli into capillaries surrounding the alveoli.
What large molecules need help getting across cell membrane?
In general, molecules that cannot diffuse across the cell membrane are either very large, such as starches and fats, or very polar.
What explains why oxygen molecules diffuse across a cell membrane while glucose molecules do not?
Glucose is too big to pass through.
What can diffuse directly across the plasma membrane of a eukaryote cell?
Most small non polar molecules can diffuse across the membrane. Water is polar but diffuses across the cell through aquaporins. There are also proteins that actively transport substances across the cell membrane such as ions (ex.The Na/K pump). It can get a little confusing. I tried to be as simple as possible. I don't know if this is what you were looking for.

CO2, H2O, and O2 can all diffuse across a cell membrane. Also, small polar molecules (uncharged) and hydrocarbons easily diffuse across.
Why do sugar molecules not diffuse through a plant cell membrane?
Sugar molecules do not diffuse through a plant cell membrane because they are too large and polar to pass through the hydrophobic interior of the lipid bilayer. Instead, sugar molecules are transported across the membrane by specific transport proteins, such as sugar transporters, that facilitate their movement into the cell.
