What else can I help you with?
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.
Can ions diffuse through a membrane?
Yes, ions can diffuse through a membrane.
Which molecule would be unable to diffuse through a cell membrane?
A molecule that is too large or charged would be unable to diffuse through a cell membrane.
What substance most easily travel across a cell membrane?
Substances that pass most readily into a cell are ions. They are transferred through ion channels that are made specifically for this purpose.
What substances diffuse into and what diffusen out of cells?
The substances flow from high concentration to low concentration through channels found in the cell membrane. Basically like a bridge.
Which substances did not diffuse the membrane?
starch doesnt diffuse through the dialysis membrane.
What type of epithelial tissue allows substances to readily diffuse through it?
simple squamous

Can ions diffuse through a membrane?
Yes, ions can diffuse through a membrane.
What type of substances pass through the membrane by facilitated diffusion?
soluble materials which can diffuse passively .
What substances easily diffuse a class of cell membrane?
Lipid-soluble substances, such as oxygen, carbon dioxide, and small non-polar molecules, easily diffuse across the cell membrane. These substances can pass through the lipid bilayer of the membrane without the need for specific transport proteins.
What characteristics is more likely to make a substance diffuse through the cell membrane?
Size. Actually very few substances are able to diffuse across the menbrane, most must be transported ie facilitated diffusion, active transport, or receptor-mediated endocytosis. Carbon dioxide, oxygen, water, and some lipid substances are able to diffuse across the membrane
How does lipid solubility affect the ability of substances entering a cell?
Lipid-soluble substances can easily pass through the cell membrane due to the presence of phospholipids that make up the membrane. These substances can dissolve in the lipid bilayer and diffuse through it, allowing them to enter the cell more readily. In contrast, substances that are not lipid-soluble may require specific transport mechanisms to facilitate their entry into the cell.
What lets substances like food and oxygen diffuse into body cells?
The semi-permeable membrane in cells. Allows some substances to go through and not others.
Which substance did not diffused through the membrane?
starch doesnt diffuse through the dialysis membrane.
What type of compound would easily diffuse into the cell?
Small, nonpolar molecules such as oxygen and carbon dioxide can easily diffuse into the cell membrane due to their ability to pass through the lipid bilayer. Hydrophobic compounds also diffuse across the membrane more readily than hydrophilic compounds.
What will not diffuse through the cell membrane?
Glucose
