What substance will diffuse through a membrane?
Substances that are small, nonpolar, and uncharged will diffuse through a membrane easily. This includes gases like oxygen and carbon dioxide, as well as small lipophilic molecules. Larger or charged molecules may require assistance from transport proteins to cross the membrane.
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.
Name 3 particles that are small enough to diffuse freely across the cell membrane?
H2O CO2 O2 hope this helps
The part of the cell that is in most direct contact with the environment is the?
The cell membrane, which surrounds the cell and is responsible for which molecules are allowed to diffuse into or out of the cell and which molecules are impermeable to the membrane
The statement below refers to a structure of the cell oxygen diffuse through this structure but sodium ion may need active transport which structure is this statement most likely referring to?
a semipermeable membrane
What explains why oxygen molecules diffuse across a cell membrane while glucose molecules do not?
Glucose is too big to pass through.
What statement explains why oxygen molecules easily diffuse across a cell membrane well glucose molecules do not?
Oxygen molecules are small and nonpolar, allowing them to easily diffuse through the lipid bilayer of the cell membrane without the need for transport proteins. In contrast, glucose is a larger, polar molecule that cannot passively diffuse through the membrane; it requires specific transport proteins to facilitate its movement into the cell. This difference in size and polarity accounts for the varying ease of diffusion for these two substances.
What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.
Statement explains why oxygen molecules easily diffuse across the cell membrane while glucose molecules?
Oxygen molecules easily diffuse across the cell membrane due to their small size and nonpolar nature, allowing them to pass through the lipid bilayer without assistance. In contrast, glucose molecules are larger and polar, requiring specific transport proteins to facilitate their movement across the membrane. This difference in molecular size and polarity determines the mechanisms by which these substances enter or exit cells.
How do you use diffuse in sentence?
Oxygen molecules diffuse across the membrane.
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.

What molecule is able to easily diffuse across the cell's membrane?
Carbon dioxide, oxygen and some nonpolar molecules diffuse easily.
