What is Isotonic solution? in Biology.?

Answer 1

An isotonic solution has an equal amount of dissolved solute in it compared to the things around it. Typically in humans and most other mammals, the isotonic solution is 0.9 weight percent (9 g/L) salt in aqueous solution, this is also known as saline, which is generally administered via an intra-venous drip. It is a medium between hypotonic and hypertonic solutions. Red blood cells normally exist in a 0.9 percent salt solution (saline) with the same concentration of salt in the outside solution.

Answer 2

Isotonic In Biology

Answer 3

A solution that has the same percentage salts as the body or cells being exposed to it. If a solution is not isotonic, water will tend to flow from the less concentrated portion to the more concentrated to dilute it. Through a cell membrane this can burst the cell. Also used to replace fluids in the human body where burns or extreme exercise have depleted the body and adding a non-isotonic fluid would mess up the cells.

Answer 4

In general chemistry terms, it means having the same concentration.
In general biology terms, an isotonic cellular milieu occurs when an equal solute concentration exists inside and outside the cell. In practical clinical terms, an isotonic solution has the same overall concentration of solutes as the usual aqueous (watery) part of blood.

"Normal" saline is an example of an isotonic salt solution:
0.9% w/v of NaCl .

Answer 5

Isotonic literally translates to equal solution. The term is used in several domainsCell biology
An isotonic cellular environment occurs when an equal solute concentration exists inside and outside the cell. Water molecules flow in and out at an equal rate by osmosis, causing the cell size to stay the same. It will not lose or gain any solutes. Plant cells in an isotonic environment are flaccid, and they will wither. The equilibrium of water movement is unable to provide plant cells with internal pressure for structural support, and therefore plants prefer to live in a hypotonic environment. In this situation, the concentration of solutes inside plant cells is higher than outside, and the plants use active transport to transport solutes in. This also ensures the concentration of water will be higher outside plant cells than inside which insures plant health.


[edit] Bio-chemistry

[edit] Athletics
This term is also used in relation to a sports drink with balanced mineralised levels mimicking the osmolality of blood. This property is claimed by their advertising campaign to increase physical endurance. The limited (6 rowers) scientific study they quote however attributes the 10% increase in endurance over water to the higher carbohydrate content.[1]


[edit] Exercise Physiology
The term Isotonic refers to a muscle contraction, either eccentric or concentric, that is not speed limited. The application of force results in external movement. Other examples include constant resistance exercise, variable resistantce exercises, plyometrics and proprioceptive neuromuscular facilitation

Answer 6

It means it has the same concentration of a solute compared to something else for instance a solution of 0.9% of NaCl(a solute) in water is isotonic to human body fluids.

Answer 7

Same as above. Murine and similar products are buffered isotonic soloutions.

A) hypertonic to fresh water but hypotonic to the salt solution - is correct Water enters when in distilled water because water is hypotonic to the cells which is another way to say that the cells are hypertonic to the water. Water leaves the cells when in a salt solution because the salt is hypertonic to the cells which is another way to say that the cells are hypotonic to the salt .

Answer 9

Yeah I see where you get that from considering that Hypertonic means that it is full of water as opposed to hypotonic having less water. Is your review exam done by ur teacher/prof?

Answer 10

a solution with the same concentration throughout
