Particles in a given medium stop moving across the membrane during diffusion when a state of equilibrium is reached, that is when the number of particles on either side of the membrane equalizes.
When will water stop moving across a membrane when the water concentration is equal on both sides.
molecules stop moving in the cell membrane when the molecules get to big that they have to get out of the cell membrane.
When one side has the same amount of water and solutes as the other side.
Osmosis
We generally use the term "tonic" when referring to the effects of osmosis across a real biological membrane. Osmosis is the movement of water across a membrane. We usually have osmosis when the concentration of solutes on each side of the membrane are different so water diffuses from the side with lower solute concentration to the side with higher concentration and this usually continues until we have equilibrium and no more water diffuses across. This environment is called an isotonic environment. ("iso" is Greek for similar or equal)
It depends on what is moving across the membrane. Some molecules use transport proteins and the cell would need those embedded in the membrane. Water doesn't need them and it freely moves in and out.
The unassisted diffusion of solutes through the plasma membrane is called simple diffusion. Solutes transported this way are either lipi-soluble (fats, fat-soluble vitamins, oxygen, carbon dioxide) or small enough to pass through the membrane pores (some small ions such as chloride ions, for example).
osmosis
True.
When will water stop moving across a membrane when the water concentration is equal on both sides.
When will water stop moving across a membrane when the water concentration is equal on both sides.
yes
Yes it is true.
when your body shuts down
The term used is osmosis. the direction of movement across the membrane is dependent on the concentration of solutes (known as the solute potential) which directly effects the osmotic potential.
osmosis is a special type of diffusion that involves water moving across a cell membrane hopefuly this helped :)
glomerular hydrostatic pressure (glomerular blood pressure)
osmosis
Must be that pressure is equal on both sides...
There are three classes of membrane transport proteins that permit water and solutes to bypass the lipid portion of the cell membrane. They are uniporters, symporters, and antiporters.
