When the concentration of molecules is the same throughout a space?
When the concentration of molecules is the same throughout a space?
Transport Terms
| A | B |
|---|---|
| cytolysis | the bursting of a cell |
| equilibrium | (in biology) a state that exists when the concentration of a substance is the same throughout a space |
| facilitated diffusion | the transport of substances through a cell membrane along a concentration gradient with the aid of carrier proteins |
Do molecules always move from high to low concentration?
molecules move from high concentration to low concentration. A few molecules, such as the sugar glucose, seem to pass through the cell membrane much more quickly than they should. One might think that these molecules are too large or too strongly charged to cross the membrane, and yet they diffuse across quite easily.
When a molecule are even throughout a space it is called?
When the molecules are evenly spread throughout the space, the water will become an even color. This process of molecules moving from an area where there are lots of molecules to an area where there are fewer molecules is known as diffusion.
What is the difference in concentration across space?
A physical space in which there is a different concentration of a single substance is said to have a concentration gradient.
When the concentration of particles is the same on both sides the cell has reached?
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. At equilibrium, movement of molecules does not stop.
When the concentration of molecules on both sides of a membrane is the same the molecules will?
During diffusion, when the concentration of molecules on both sides of a membrane is the same, the molecules will continue to move across the membrane…
What is high concentration and low concentration?
High concentration means the amount of solute is high in the solution and low concentration means it is low. Amount of solvent is high in low concentration and low in high concentration of solute.
When the concentration of solute is the same throughout?
Tonicity and cells
| Tonicity of solution | Solute concentration | Water moves… |
|---|---|---|
| Hypertonic | Higher solute in solution than in cell | Out of the cell |
| Isotonic | Equal amounts of solute in cell and solution | Into and out of cell at the same time |
| Hypotonic | Lower solute in solution than in cell | Into the cell |
What is another way to describe molecules moving from high to low concentration?
Diffusion. During diffusion, substances move from an area of high concentration to an area of low concentration, until the concentration becomes equal throughout a space. Image showing the process of diffusion across the plasma membrane. Initially, the concentration of molecules is higher on the outside.
What is it called when molecules move from high to low concentration?
Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration.
When the concentration of molecules on both sides of the membrane is the same the solution outside the membrane is?
QUSTION: When the concentrations of solutions are the same on both sides of a membrane the two solutions are. Answer: Isotonic.
What is high concentration and low concentration in diffusion?
Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. This is due to the random movement of the molecules. The difference in the concentration of a substance between two areas is called the concentration gradient .
