When is a substance most likely to diffuse into a cell?
If there is the concentration of substance inside the cell is lesser than outside and cell membrane is permeable to the substance.
What occurs when water molecules diffuse through a membrane?
osmosis
Occurs when water molecules diffuse through a membrane?
Osmosis
What is a transport process by which gases move through a membrane?
Simple Diffusion
What substance can diffuse through a differentially permeable membrane?
Diffusion across a membrane in biology is referred to as 'osmosis' & osmosis is the process by which solvent molecules move from a region of high conc. to low concentration and this can therefore occur only in one direction at a time for a perticular solution. this is a really smart answer im surprised
Which substance did not diffused through the membrane?
starch doesnt diffuse through the dialysis membrane.
What substance is most likely to passively diffuse across the plasma membrane by dissolving in the membrane?
Lipid-soluble molecules such as O2 and CO2 diffuse freely through the plasma membrane.
Which substances did not diffuse the membrane?
starch doesnt diffuse through the dialysis membrane.
What is the membrane said to be if a substance is able to diffuse across a membrane?
selectively permeable
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
Why do sugar molecules not diffuse through a plant cell membrane?
The membrane is semi-permeable. Sugar molecules are too large to diffuse through.
How can some substance diffuse through a cell membrane at faster rate than by diffusion alone?
In facilitated diffusion, there are temporary openings in the cell membrane that enable certain molecules to pass through quickly.
What will not diffuse through the cell membrane?
Glucose
What does not freely diffuse through the plasma membrane?
glucose
Does oxygen diffuse through a semipermable membrane?
yes
In Osmosis does salt diffuse through a membrane?
Yes
