How is a concentration gradient related to the process of diffusion? | Socratic
Higher concentration gradients will result in higher rates of diffusion. As the molecules move the gradient evens out until equilibrium is reached. Can you explain to me the difference between diffusion, osmosis and active They do this until equilibrium is reached and the concentration gradients on either. Diffusion will continue until the concentration gradient has been eliminated. At equilibrium, movement of molecules does not stop. What is the main difference between simple diffusion and facilitated diffusion? What is a.
Since you have more of these particles here and they're all bouncing around in different directions randomly, you have a higher probability of things moving from the left to the right than from the right to the left. You will have things move from the right to the left, but you're going to have more things, so you'll have a higher probability of things, moving from left to right.
And so if you let some time pass, then they become more uniformly spread across a container. They have moved down their concentration gradient to make things more uniform. Now, what's interesting about this diagram is I've introduced a second particle, these big yellow particles. And we see that their concentration gradient is going in the other direction. So we have a low concentration, in fact we have no, on the left-hand, we have none of the yellow particles on the left-hand side, and we have a high concentration on the right-hand side.
What’s the difference between diffusion and osmosis
So their concentration gradient goes from right to left. And the whole point of this video is to show that each particle moves down its unique concentration gradient, assuming that it's not blocked in some way, it's going to move down its unique concentration gradient irrespective of what the other particles are going to do, for the most part. And so we see the yellow particles are going to move from high concentration, to low concentration.
They're going to move, they're going to diffuse from right to left. And once again, there's no magic here.

It's not like this molecule is saying, oh, I've got seven other of my friends here, it's getting too crowded, I see them, I'm claustrophobic, let me move over to the left-hand side. The factors affecting diffusion are: Spraying a perfume in a room will make it smell nice for a little while, but over time diffusion will distribute the odor molecules until their concentration is imperceptible to the human nose.
Dropping food coloring in a cup of water, which will change the color of the whole solvent wateris another great example of diffusion Diffusion is a widespread and important process for both nonliving and living systems. To enter and exit a cell, substances like water or nutrients have to pass through the semipermeable membrane. Diffusion is one of the processes that enable this.
A semipermeable or selectively permeable membrane is a membrane that allows some substances to pass through easily while other substances travel through very slowly or not at all.

Since diffusion occurs under a variety of conditions, scientists classify several types of diffusion. Simple diffusion is the most common kind of diffusion, where substances are transported without the help of proteins. Dialysis is the diffusion of solutes across a selectively permeable membrane.
Osmosis is usually defined as the diffusion of water, the solvent of choice in all living systems, across a selectively permeable membrane. What is Osmosis Osmosis, a type of diffusion, represents the movement of water across a partially-permeable membrane, from an area of high water concentration to an area of low water concentration.
Osmosis takes places in all cells. For instance, when placed in water, red blood cells will let the water creep through their membrane. When placed in a concentrated solution of sugar, the red blood cell actually shrinks because the water moves out by osmosis towards the area of lower water concentration.
This is why the cells appear wrinkled when viewed through a microscope.

Luckily, this never happens inside the body because the kidneys make sure the concentration of the blood stays about the same as the concentration of the solution inside the red blood cell.
Unlike red blood cells, plant cells have a far stronger and more rigid cell wall on the outside of the cell membrane. This enables the plant cells to absorb more water by osmosis without bursting.
If plant cells lose too much water by osmosis, they become less rigid, and eventually, the cell membrane shrinks away from the cell wall.
When osmosis is used to equalize concentrations on both sides of the membrane, it exerts a force called osmotic pressure. For instance, picture two compartments in a tank separated by a semipermeable membrane that only allows water molecules to pass through.
One compartment is filled with a salt solution, while the other adjacent compartment is a pure water solution. The only way equilibrium can be reached is by transporting water from the pure water compartment to the saltwater compartment. In doing so, osmosis raises the level of liquid in the saltwater compartment until enough pressure caused by the difference in levels between the two compartments stops the processes.
The pressure it takes to reach this equilibrium is called the osmotic pressure. In other words, instead of seeking an equal balance of solvent and solute in both solutions, reverse osmosis separates the solute from the solvent.
Reverse osmosis is very handy for applications like water desalination removing salt from seawater.
