What is the relationship between a concentration gradient and the rate of diffusion?
the concentration gradient is about both active and passive transport
equilibrium is when the is no concentration gradient
but equilibrium is a transient condition
this is because molecules are in constant random motion
the electrons spinning around the molecule's nucleus keep them in random motion
since they're in random motion they constantly bump into each other
since the constantly bump into each other they try to spread out
this describes the force of diffusion
so, when the molecules are bunched together they have high concentration
they'll try to spread out, which moves them to lower concentration
this means they have moved down the concentration gradient
it is passive transport because these was no energy used to make it happen
as long as the molecules are small enough
in other words as long as there's no large molecules dissolved in the solution
then the solution and its solutes are free to diffuse
but any large molecules dissolved in the solution will not pass through a semipermeable membrane

What is the difference between the concentration of a particular molecule in one area and the concentration in an adjacent area?
The concentration gradient is the difference in concentration of a molecule between one area and an adjacent area. This difference creates a gradient that drives the movement of molecules from an area of higher concentration to an area of lower concentration, a process known as diffusion.
What is concerntration gradient?
As used in the process of diffusion, the concentration gradient is the graduated difference in concentration of a solute within a solution (as expressed per a unit distance). Molecules tend to move from areas of greater concentration to areas of lesser concentration. i.e. down the gradient.
What is a concentration gradient?
A concentration gradient is the difference in concentration of a substance between two regions. This difference drives the movement of molecules or ions from an area of higher concentration to an area of lower concentration, a process known as diffusion.
Rate of diffusion is dependent upon molecular?
size, temperature, and concentration gradient. Smaller molecules diffuse faster than larger molecules, as they can more easily navigate through the spaces between other molecules. Higher temperatures increase the kinetic energy of the molecules, leading to faster diffusion. A steeper concentration gradient, where there is a large difference in concentration between two areas, also promotes faster diffusion.
What is the relationship between concentration gradient and active and passive transport?
Concentration gradient= the relative amount of a given substance contained within a solution or in a particular volume of space; the amount of solute per unit volume of solution • the action of strengthening a solution by the removal of water or other diluting agent or by the selective accumulation of atoms or molecules. Diffusion= net movement of particles from an area of higher concentration to an area of lower concentration The concentration gradient is the amount of substance in a particular area (the substance stays together) Diffusion is when the substance gradually spreads out in its' area. e.g: If you spray perfume in a room, eventually you can smell it all around the room because of diffusion. However if you spray the perfume in the room and it just stays in one spot, that is the concentration gradient.
Why is diffusion affected by a decrease in concentrated gradient?
Diffusion is driven by the concentration gradient, so a decrease in concentration gradient slows down the rate of diffusion. This is because there is less of a difference in concentration between two areas, leading to fewer particles moving from high to low concentration.
Diffusion continues until there is no?
Diffusion continues until there is no longer a concentration gradient present between the two regions. Once equilibrium is reached, the molecules will be evenly distributed throughout the system and diffusion will stop.
What forms a concentration whenever there is a difference in concentration between one place and another?
A concentration gradient forms when there is a difference in concentration between one place and another.
How does gradient affect diffusion?
A concentration gradient is a difference in concentration across a space. It affects diffusion and osmosis because both of these passive transports move down their concentration gradients, or from an area of high concentration to low concentration.
What kind of concentration forms whenever there is a difference in concentration between one place and another?
A gradient forms when there is a difference in concentration between two places. This gradient drives the movement of substances from areas of higher concentration to areas of lower concentration through processes such as diffusion or osmosis.
What controls the rate of diffusion?
The rate of diffusion is controlled by factors such as concentration gradient, surface area available for diffusion, temperature, and the size of the molecules involved. A steeper concentration gradient, larger surface area, higher temperature, and smaller molecules generally lead to faster diffusion rates.
What is the relationship between the relative concentrations of molecule X and the use of ATP for diffusion?
The relative concentration of molecule X determines the direction and rate of diffusion; if there is a greater concentration gradient of molecule X, more ATP will be used to facilitate the diffusion process. ATP is used to power certain transport proteins that move molecules against their concentration gradient, so the amount of ATP used is dependent on the concentration gradient of molecule X.
What is the difference between the concentration of a particular molecule in one area and the concentration in an adjacent area?
The concentration gradient is the difference in concentration of a molecule between one area and an adjacent area. This difference creates a gradient that drives the movement of molecules from an area of higher concentration to an area of lower concentration, a process known as diffusion.
What does concentration gradient have to do with diffusion of substances across the cell membrane?
The concentration gradient refers to the difference in concentration of a substance between two regions. In the context of cell membranes, substances tend to move from areas of higher concentration to areas of lower concentration to reach equilibrium. This movement is known as diffusion and it is driven by the concentration gradient.
What is concerntration gradient?
As used in the process of diffusion, the concentration gradient is the graduated difference in concentration of a solute within a solution (as expressed per a unit distance). Molecules tend to move from areas of greater concentration to areas of lesser concentration. i.e. down the gradient.
Compare and contrast between osmosis and facilitated diffusion?
Osmosis is when a solvent moves from a lower concentration to a higher concentration. Facilitated diffusion is when a solvent moves down the concentration gradient through carrier molecules.
What is the difference in concentration between a region of high concentration and one of lower concentration?
The concentration gradient represents the difference in concentration between a region of high concentration and one of lower concentration. This gradient drives the diffusion of particles from areas of high concentration to areas of low concentration until equilibrium is reached.
