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

When could diffusion be dangerous?
pollution that can make us medically unwell is an effect of diffusion
What is the effect of heat on beetroot?
The effect of heat on beetroot is that the membrane becomes impacted. It causes the membrane to be more permeable.
What is the effect of hypertonic solution on rbc?
A blood cell immersed in a hypertonic solution will cause water to move out of the cell, thereby causing it to shrivel. Osmotic pressure is water's tendency to seek to equalize its own concentration across a semipermeable membrane (like the cell membrane of a blood cell). So in a hypertonic solution (relative to the solution inside the blood cell), there are less particles of water per particle of solute. This means the water concentration inside the blood cell is higher, and mother nature will have none of that. So water will move out of the cell, seeking to equalize its concentration across the cell membrane. If the membrane is also permeable to solutes in the hypotonic solution, they will move across the membrane following their own chemical and electromagnetic concentration gradients.
What is the effect of glycerol on a cell membrane?
It interact with membrane to increase stiffness
Does distance effect rate o diffusion?
Yes if the distance that the molecule has to travel is long then the rate of diffusion will be slower.
The movement of particles from a high concentration to a low concentration?
diffusion
What happen during the facilitated diffusion?
Facilitated diffusion occurs against the osmotic potential/concentration gradient and requires energy at the expense of the ATP hydrolysis. There are several way in which this diffusion could occur in the cells. The first one being the ion exchangers. The ion exchangers are coupled with ATPase activity and they exchange ion(s) across the membrane. The most classical example of ion exchanger is the Na+/K+ ion exchanger and Ca+ ATPase. Other way of the facilitated diffusion in the ion channel. These could be voltage gated channel that open in response to the change in the membrane potential and the other being ligand gated channel that operate under the effect of ligand binding.
What are 3 factors that can have a effect on the rate of diffusion?
Diffusion rate varies with concentration difference, temperature and dimension of transfer path (area or distance).
What happens to a particle in diffusion?
When particles diffuse they break apart, down into simpler substances. Diffusion is the net movement of molecules from high to low concentration through random motion. From the particle point of view it just moves about at random (as usual) but the overall effect is for the particles to spread out evenly.
What is the relationship between diffusion and osmosis?
First off, osmosis is the process by which H2O molecules DIFFUSE across a cell membrane from an area of higher concentration to an area of lower concentration. Therefore, osmosis is related to diffusion because osmosis is a type of diffusionwell if you look at it this way: -they both travel from region of high concentration to high concentration-they both involve the movement of something-they are both examples of passive transport-they both pass through a semi-permeable membrane
What factors affect the diffusion of water?
One of the factors that affect the diffusion of water through a membrane by osmosis is the permeability of the membrane. The amount of water on each side of the membrane may also have an effect on water's diffusion. Water will diffuse to the side with little water to even out the concentration.
What is the effect of the chloride ion concentration on its rate of diffusion in agar?
it will diffuse faster becuase it is more concentrated
Should NaCl have an effect on Glucose diffusion?
No, not really. Diffusion works when molecules move from an area of higher concentration to an area of lower concentration. They move independently of one another. So even if you have a high level of NaCl, the glucose concentration will diffuse in the same manner.
How does osmosis diffusion hypotonic hypertonic and isotonic solutions relate to the cell?
osmosis is the diffusion of water across a membrane. Regualtes cells osmotic pressure. diffusion- simply means that a substance travels down its concentration gradient to areas of lower solute concentration. Osmosis is a type of diffusion. hypotonic solution: if a cell is placed in an hypotonic solution (a solution with less solute concentration) the cell will swell (and eventually lyse) as water rushes into it to dilute the hypertonic environment in the cell. hypertonic solution: if a cell is placed in a hypertonic solution thecell will shrivel up as water leaves it to dilute the higher solute concentration outside of the cell.
How does boiling a potato effect osmosis?
Boiling the potato destroys the cell membrane which is a partially permeable membrane. Thus osmosis is unable to occur as osmosis occurs through a partially membrane and only diffusion would occur.
Marijuana cocaine and heroin have the same effect as alcohol on a driver's -?
Both cocaine and heroin will effect your concentration. You do not want to take these substances and then get behind a wheel.
What is the definition of diffuses?
DiffusionPhysics and ChemistryDiffusion is the movement of particles from an area of high concentration to an area of low concentration. Diffusion is not to be confused with osmosis, which is the movement of water through a semi-permeable membrane. However, osmosis is a special case of diffusion.Lighting (as in Photography)Diffusion means to scatter light. A similar effect can be achieved by placing a Gelatin silk plate over a camera or projection lens.Generally, from the eyes of a 7th grader, diffusion is when molecules of which are concentrated in one area spread out like if you spray air-freshener in one side of a room and the scent spreads throughout the room that is diffusion.(See related link below for more information from Answers.com)
