What condition does diffusion eventually lead to?
Diffusion eventually leads to equilibrium if other influences are absent, which means the concentration of molecules will be the same throughout the space they occupy.
What is the result of diffusion?
Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes "down the concentration gradient." The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane.
Under what conditions would simple diffusion occur?
Simple passive diffusion occurs when small molecules pass through the lipid bilayer of a cell membrane. Facilitated diffusion depends on carrier proteins imbedded in the membrane to allow specific substances to pass through, that might not be able to diffuse through the cell membrane.
What does it mean to say that diffusion eventually results in equilibrium quizlet?
Terms in this set (29) Explain why diffusion eventually results in equilibrium? Diffusion will occur until two areas have reached equal concentrations. Identify whether all molecules diffuse through all cell membranes.
Does diffusion go from high to low concentration?
Osmosis And Diffusion Definitions Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
What is the cause of diffusion?
The kinetic energy of the molecules results in random motion, causing diffusion. In simple diffusion, this process proceeds without the aid of a transport protein. it is the random motion of the molecules that causes them to move from an area of high concentration to an area with a lower concentration.
What does diffusion move?
Osmosis And Diffusion Definitions Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
Why does diffusion happen?
Diffusion happens because gases and liquids move from place to place in quick random motions. When this happens, the particles collide, which in turn makes them change directions. The process of diffusion occurs on its own without any help from shaking or stirring.

Why does diffusion occur quizlet?
Diffusion occurs because molecules are always bumping into each other and moving from one to another concentration.
Why does diffusion eventually result in equilibrium?
Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes "down the concentration gradient". The end result is an equal concentration, or equilibrium, of molecules on both sides of the membrane.
What is in hypertonic solution?
Hypertonic solution: A solution that contains more dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood.
What is the process of diffusion?
diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room.
What causes diffusion quizlet?
What causes diffusion? Molecules constantly bumping into one another, which causes them to push away from each other and move to an area of lower concentration.
What happens when cell undergoes diffusion?
The kinetic energy of the molecules results in random motion, causing diffusion. In simple diffusion, this process proceeds without the aid of a transport protein. It is the random motion of the molecules that causes them to move from an area of high concentration to an area with a lower concentration.
What substances move by diffusion?
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ).
Where does diffusion happen?
Notably, diffusion takes place when a new chemical enters a cell's cytosol, the fluid part of a cell's insides. After new molecules enter a cell, they diffuse evenly through the cytosol. Note that they don't enter the cell through diffusion; again, that's osmosis.
Which conditions would cause diffusion to happen more quickly quizlet?
The higher the temperature, the higher the rate of diffusion, due to the particles having more kinetic energy and moving faster.
What is equilibrium in diffusion?
Definition. The state in which the concentrations of the diffusing substance in the two compartments are the same or become equal.
How can you tell diffusion has reached equilibrium?
As a result, the particles tend to move from an area where they are more concentrated to an area where they are less concentrated, a process known as diffusion (dih-FYOO-zhun). When the concentration of the solute is the same throughout a system, the system has reached equilibrium.
What is hypotonic condition?
If a cell is placed in a hypotonic solution, there will be a net flow of water into the cell, and the cell will gain volume. If the solute concentration outside the cell is lower than inside the cell, and the solutes cannot cross the membrane, then that solution is hypotonic to the cell.
What is hypertonic and isotonic?
Hypertonic has a higher concentration of fluid, sugars and salt than blood. Isotonic has similar concentration of fluid, sugars and salt to blood.
What diffusion means?
Diffusion is defined as the movement of individual molecules of a substance through a semipermeable barrier from an area of higher concentration to an area of lower concentration (34).
What is diffusion quizlet?
Diffusion. Movement of particles or molecules from an area of high concentration to an area of low concentration.
What is diffusion process?
diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room.
What is diffusion and why does it happen?
Think of diffusion as a "drifting" movement. While it refers to a random and unguided process, and one that does not require an input of energy, it does follow one rule: Particles move from areas of higher concentration to areas of lower concentration, even while individual molecules are free to move in all directions.
Which conditions would cause diffusion to happen more slowly?
Select conditions that would cause diffusion to happen more slowly: –The solvent contains molecules similar in size and shape to the diffusing molecules. -The molecules are diffusing through a high density liquid.
In which of the following situations would diffusion occur the fastest?
Diffusion occurs faster in higher temperatures because the speed of the particles rises, as does the temperature. What is the Diffusion gradient? The diffusion gradient is the difference between two concentrations.
When diffusion has reached equilibrium would the molecules stop moving?
In diffusion the net movement or overall, of a substance will travel from an area of high concentration to an area of low concentration. The molecules will not stop moving. The molecules are continuously moving even when they have reached equilibrium.
What is isotonic and hypertonic?
Hypertonic has a higher concentration of fluid, sugars and salt than blood. Isotonic has similar concentration of fluid, sugars and salt to blood.
