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 able to diffuse across a membrane then the membrane is said to be what?
selectively permeable
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+...)
Can all molecules diffuse through all cell membranes?
No, there are specific cell membranes that allow only certain molecules to pass through. Some stay open and others must be opened ( like a gate ).
What substance will diffuse through a membrane?
The three substances that can diffuse through a cell membrane are CO2, O2, AND H2O.
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?

Which substance did not diffused through the membrane?
starch doesnt diffuse through the dialysis membrane.
If a substance is unable to diffuse across a membrane we say the membrane is?
osmotically active
Where do particles of the dissolving substance go in the liquid?
They break up into individual molecules (or ions) and diffuse throughout the liquid.

Do water molecules passively enter and leave cells through the plasma membrane?
Yes, the direction of the flow depends on the contentration of water on the out side and the inside of the cell's membrane.
