What directions do molecules move if the concentration is equal on both sides of a membrane?

they should move neither way. Rather, some molecules will move either side, but the concentration will stay the same

What best describes a cell that is isotonic for a substance?
The solute concentration is equal on both sides of the cell membrane
Where and when does osmosis occur?
Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane .
When will water and solutes stop moving across a membrane?
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.
Is it true that once equilibrium is reached roughly equal numbers of molecules move in either direction across a semipermeable membrane?
Yes, when equilibrium is reached, solute particles continue to diffuse across the membrane in both directions. Cells are always moving.
What is osmosis a type of?
Diffusion. Osmosis is the diffusion of water across a membrane.Osmosis is a special type of diffusion. It is the movement of water molecules only from a solution of higher water potential to a solution of lower water potential across a selectively permeable membrane.The characters in bold indicate the specificity of osmosis as compared to diffusion.(Biology, chemistry) diffusion of molecules through a semipermeable membrane from a place of higher concentration to a place of lower concentration until the concentration on both sides is equal
How is osmosis related to water?
Osmosis is when water molecules pass through a membrane. For example, if there is more salt outside a cell then inside it, the process of osmosis transports water molecules outside the cell to equalize the concentration of salt. WordNet's definition: diffusion of molecules through a semipermeable membrane from a place of higher concentration to a place of lower concentration until the concentration on both sides is equal
In general the net movement of small uncharged atoms and molecules through the membrane of a cell will occur until?
Molecules will move into or out of the cell until it becomes isotonic to its surroundings. This means that the concentration of the molecules inside the cell is equal to the concentration of the molecules outside the cell.
What happens to a higher concentration of dissolved molecules on one side of a cell membrane during the process of diffusion?
the side of the cell membrane with the higher molecule concentration moves molecules to areas of lower concentration during diffusion until an equilibrium is reached between both sides of the membrane.
What best describes a cell that is isotonic for a substance?
The solute concentration is equal on both sides of the cell membrane
What happens in a cell transportation lab report?
When a cell membrane is said to be selectively permeable, it means that the cell membrane controls what substances pass in and out through the membrane. This characteristic of cell membranes plays a great role in passive transport. Passive transport is the movement of substances across the cell membrane without any input of energy by the cell. The energy for passive transport comes entirely from kinetic energy that the molecules have. The simplest type of passive transport is diffusion, which is the movement of molecules from an area of high concentration to an area of lower concentration. Diffusion moves down the concentration gradient, which is the difference in the concentration of molecules across a space. Osmosis is a type of diffusion in which water molecules move down the concentration gradient. When the concentration of solute molecules outside the cell is lower than the concentration of solute in the cytosol , the solution outside is hypotonic to the cytosol. If the concentration of solute molecules is higher outside of the cell, the solution outside is said to be hypertonic. The solution outside is isotonic if the concentration is equal on both sides of the cell membrane.
How does a cell each equilibrium?
Molecules tend to travel from a concentration from high to low. A cell will reach equilibrium when the concentration gradient has become equal on both sides of a cell (inner and outer membrane). A cell will reach what is called "dynamic equilibrium" when the concentration gradient of a cell is equal, but molecules still move back and forth in the same proportions.
When solute concentration is equal on both sides of a membrane it is?
Isotonic
What effect does diffusion have on the concentration of substances on either side of a membrane?
Diffusion is the movement of particles from a region of higher concentration to a region of lower concentration. If no other factors are involved, the concentration in the higher region will fall and the concentration in the lower region will rise until the concentration is equal on both sides of the membrane. Diffusion will continue, but on average equal numbers of particles will diffuse in both directions during equal periods of time. This is called a dynamic equilibrium. For a basic introduction to diffusion see: http://www.bbc.co.uk/schools/gcsebitesize/biology/cellprocesses/2diffusionandosmosisrev2.shtml For more detail see: http://www.blobs.org/science/article.php?article=20
Why did whole milk move?
The whole milk moves because of diffusion.The molecules of milk diffuse thorugh the water as in simple diffusion, molecules diffueses from where it is more concentrated to where it is less concentrated to where it is less concentrated (diffusing down its concentration gradient). This leads to dynamic equilibrium; the solute molecules of mile continue to cross the membrane but at equal rates in both directions. Diffusion is a spontaneous process, needing no input of energy. No work must be done to move substances down the concentration gradient.
What is Equal movement of molecules called?
The equal movement of molecules would be describing an "isotonic" state, where concentration gradients are equal, and a state of equilibrium is created.
