What Is Tonicity Quizlet?

What is tonicity quizlet? Tonicity. A description of the relative solute concentration in a solution as compared to another solution. Equilibrium. The condition that exists in system when there is a relatively equal distribution of a particular molecule. Hypertonic.

Also to know is, What is tonicity and how does it affect the condition of the cell quizlet?

When a cell is placed in a highly concentrated solution, water molecules will move out of the cell causing it to shrink and die.

Moreover, Which of the following is the measure of the tonicity of a solution? The measure of the tonicity of a solution, or the total amount of solutes dissolved in a specific amount of solution, is called its osmolarity. Three terms—hypotonic, isotonic, and hypertonic—are used to relate the osmolarity of a cell to the osmolarity of the extracellular fluid that contains the cells.

As well as, Which membrane transport process will continue on even though the cell may be alive or dead?

Which membrane transport process can continue whether the cell is alive or dead? pinocytosis.

What is tonicity in biology?

Tonicity is defined as the ability of a solution surrounding a cell to cause that cell to gain or lose water (Urry et al., 2017). While osmolarity is an absolute quantity, tonicity is relative. If two solutions have the same concentration of nonpenetrating solutes, they are considered isotonic.

Related Question for What Is Tonicity Quizlet?

What is the tonicity of the cell?

Tonicity is the capability of a solution to modify the volume of cells by altering their water content. The movement of water into a cell can lead to hypotonicity or hypertonicity when water moves out of the cell.

What is tonicity of solutions?

In biology, the tonicity of a solution usually refers to its solute concentration relative to that of another solution on the opposite side of a cell membrane; a solution outside of a cell is called hypertonic if it has a greater concentration of solutes than the cytosol inside the cell.

What is an example of a hypertonic solution?

Hypertonic solutions have a higher concentration of electrolytes than plasma. Common examples of hypertonic solutions are D5 in 0.9% normal saline and D5 in lactated ringers. The administration of hypertonic solutions should be monitored extremely closely, as they can quickly lead to fluid overload.

What happens to vesicles after endocytosis?

At the beginning it is formed from the cell membrane as part of this membrane engulfs some material from outside. Then this formed vesicle is fused with other vesicles which contains digestive enzymes. The components of it are absorbed by the cell after being digested. Then it is recycled.

How are vesicles involved in endocytosis and exocytosis?

Endocytosis is the process of capturing a substance or particle from outside the cell by engulfing it with the cell membrane, and bringing it into the cell. Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell.

Does phagocytosis use vesicles?

Phagocytosis is a special form of endocytosis in which large particles such as microorganisms and dead cells are ingested via large endocytic vesicles called phagosomes.

What is an example of tonicity?

EXAMPLES. Tonicity is the reason why salt water fish cannot live in fresh water and vice versa. A salt water fish's cells have evolved to have a very high solute concentration to match the high osmolarity of the salt water they live in.

Is tonicity a form of osmosis?

The ability of an extracellular solution to make water move into or out of a cell by osmosis is known as its tonicity. If the solute concentration outside the cell is the same as inside the cell, and the solutes cannot cross the membrane, then that solution is isotonic to the cell.

How is tonicity related to osmosis?

Tonicity describes how an extracellular solution can change the volume of a cell by affecting osmosis. A solution with low osmolarity has a greater number of water molecules relative to the number of solute particles; a solution with high osmolarity has fewer water molecules with respect to solute particles.

What's the relationship between osmosis and tonicity?

“Tonicity is the ability of a solution to affect the fluid volume and pressure in a cell. If a solute cannot pass through a plasma membrane, but remains more concentrated on one side of the membrane than on the other, it causes osmosis.”

How is tonicity measured?

Tonicity is a measure of the relative concentration of non-penetrating solute on either side of a membrane. It uses the same units as molarity or osmolarity, but unlike these other measurements includes only non-penetrating solutes in the calculation. Determine the number of moles of solute.

What cells need this tonicity to be at homeostasis?

Animal cells need to be in isotonic solutions to be at homeostasis. Homeostasis is a balance and is important for all living things to maintain.

What is meant by the tonicity of a solution quizlet?

Terms in this set (28)

Osmotic pressure of a solution is the pressure that must be applied to completely stop the movement of water by osmosis. Define tonicity. Tonicity of a solution refers to the effect the non-penetrating solute concentration and movement of water by osmosis has on cell volume.

What tonicity of solution would lead to a cell shriveling quizlet?

This is an example of a hypertonic solution, which will cause the plant cells to shrivel up and die, since they need to be in a hypotonic solution to thrive. You just studied 4 terms!

Is tonicity due to a solution containing a permeable or impermeable solute?

Tonicity is a measure of the relative concentration of solute particles on either side of a semi-permeable membrane (e.g. inside a cell versus outside the cell). Only solutes that cannot cross the membrane contribute to tonicity.

How does dextrose affect tonicity?

The tonicity is determined by comparing the concentration of nonpenetrating solutes, those that cannot enter the cell, in the solution to the concentration of the cell. A solution of 5% dextrose has zero nonpenetrating solutes, and therefore, it is hypotonic.

Is D5NS a hypertonic solution?

Compared with intracellular fluids, hypertonic solutions have a higher concentration of solids. These are some examples of hypertonic solutions: D10W (dextrose 10% in water), D5NS (dextrose 5% in . 9% sodium chloride), D5 12 NS (dextrose 5% in . 45% sodium chloride), and D5LR (dextrose 5% in lactated ringer).

What is hypotonic solution example?

A hypotonic solution is a solution that has a lower concentration of solute compared to the cell. A hypotonic solution example is salt water. The salt is the solute, and the water is the solvent.
