What else can I help you with?
If a substance is able to diffuse across a membrane then the membrane is said to be what?
selectively permeable
Can ATP passively diffuse across cell membrane?
The universal energy molecule of the cell, adenosine triphosphate (ATP) cannot passively diffuse across the cell membranes. Despite its low molecular weight, ATP carries a strong negative charge making it hydrophilic and thus unable to diffuse across the lipophilic cellular membrane.
If a substance is unable to diffuse across a membrane we say the membrane is?
osmotically active
What molecules passively diffuse across the plasma membrane?
Diffusion is a type of passive transport but the answer I think you are looking for is this: water, gasses(N,O2,CO2...), and ions(K+, Na+...)
What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.
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.
What type of substances pass through the membrane by facilitated diffusion?
soluble materials which can diffuse passively .
What is the membrane said to be if a substance is able to diffuse across a membrane?
selectively permeable

Which substance did not diffused through the membrane?
starch doesnt diffuse through the dialysis membrane.
Why can oxygen diffuse across a cell membrane but a protein?
Its too large

What types of molecules can diffuse through the cell membrane without using a channel protein?
Small, non-polar molecules like oxygen, carbon dioxide, and water can diffuse through the cell membrane without the need for a channel protein. Their small size and non-polar nature allow them to passively pass through the lipid bilayer of the membrane.
Which substances did not diffuse the membrane?
starch doesnt diffuse through the dialysis membrane.
Can ions diffuse through a membrane?
Yes, ions can diffuse through a membrane.
