The cell membrane is semi-permeable which means that some thing go in and out of the cell freely and exist in to the same extent both within the cell and outside the cell. However, many things are actively transported into or out of the cell so that they exist in a higher or lower concentration within the cell in respect to the extracellular concentrations.

What is The concetration of glucose in intracellular fluid?
The concentration of glucose in intracellular fluid is typically around 1-10 mM (millimolar). This concentration can vary based on factors such as cellular metabolism, nutrient availability, and hormonal regulation.
0.9 sodium chloride solution is isotonic with extacellular and intracellular fluid what does isotonic mean?
Isotonic means that the concentration of solutes in the solution is the same as the concentration of solutes in the intracellular and extracellular fluid. This allows for balanced movement of water across cell membranes without causing them to shrink or swell.
What process is called in which water moves between the intracellular and extracellular compartments?
The process is called osmosis. It involves the movement of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration, in order to equalize the concentration of solutes on both sides of the membrane.
Is centipede digestion extracellular or intracellular?
Centipede digestion is intracellular. They have a digestive system where food is broken down within specialized cells through intracellular processes.
Difference between intracellular fluid and extracellular fluid?
Cytoplasm is the inner part of the cell or its the contents of the cell, which is surrounded by plasma membrane. While extracellular fluid is the fluid located outside of the cells and divided into 1.plasma in the blood vessel. 2.interstitial fluid between the cells.
Which electrolyte has the highest concentration in the intracellular fluid?
The electrolyte with the highest intracellular concentration would probably be considered to be sodium chloride (NaCl), or at least Na^+ cation.
What is the chloride ion concentration in intracellular fluid?
Every Laboratory has specfic values that their Lab Medicine Docs have signed off as being Normal Values, however, generally The Intracellular Concentration of Chloride in Eukaryotic Cells is 5 milliMoles. The Extracellular Concentration of Chloride is 110 mM. The Intracellular Concentration of Calcium is < 1 mM The Extracellular Concentration of Calcium is 1.8 mM
What is The concetration of glucose in intracellular fluid?
The concentration of glucose in intracellular fluid is typically around 1-10 mM (millimolar). This concentration can vary based on factors such as cellular metabolism, nutrient availability, and hormonal regulation.
What would happen to the intracellular and extracellular concentration of urea if the kidney stopped functioning?
If the kidney stopped functioning, the intracellular concentration of urea would increase due to impaired excretion. In contrast, the extracellular concentration of urea would also increase due to the diminished clearance of urea from the blood.
What is the concentration of sodium ions inside the cell is usually than the concentration of sodium ions outside the cell?
Extracellulary, Sodium is major ion. Intracellular concentration of sodium is: 12 mEq/L Extracellular concentration of sodium is: 140 mEq/L Intracellularly, Potassium is major ion. Intracellular concentration of Potassiumis: 140 mEq/L Extracellular concentration of Potassiumis: 3.5-5 mEq/L These concetrations are maintained by Na+/K+ ATPase.
What is the mechanism that restores the resting membrane voltage and intracellular ionic concentration?
Resting membrane potential is restored through the activity of the sodium-potassium pump, which actively transports sodium ions out of the cell and potassium ions into the cell. Intracellular ionic concentration is restored through various ion channels and transporters that regulate the movement of ions across the cell membrane based on concentration gradients.
Which salt solution is more likely to be isotonic to the intracellular fluids of a potato?
A 0.9% sodium chloride solution (normal saline) is more likely to be isotonic to the intracellular fluids of a potato. This concentration is similar to the overall solute concentration inside the cells of a potato, making it the best choice to prevent osmotic imbalance when the potato is immersed in the solution.
Intracellular water volume depends primarily on the concentration of?
Intracellular water volume primarily depends on the concentration of electrolytes, mainly sodium and potassium ions, which help maintain osmotic balance within the cell. These electrolytes regulate water movement across the cell membrane, influencing the overall hydration status of the cell. Disruption in electrolyte concentration can lead to cellular dehydration or swelling.
What diffusion is lower concentration to a higher concentration?
This process is called active transport, where cells use energy to move molecules against their concentration gradient, from an area of lower concentration to a higher concentration. This mechanism allows cells to maintain specific intracellular concentrations of certain molecules that are different from their surroundings.
Solution that causes no change in the intracellular volume?
An isotonic solution that has the same solute concentration as the intracellular fluid will not cause a change in the intracellular volume when introduced to cells. This is because there will be no net movement of water across the cell membrane, maintaining equilibrium. Examples of isotonic solutions include normal saline (0.9% NaCl) or Ringer's solution.
What is the most important factor in decreasing intracellular concentration of calcium ion after contraction is?
The most important factor in decreasing intracellular calcium ion concentration after contraction is the active transport of calcium ions out of the cell by the calcium ATPase pump located on the cell membrane. This pump helps in restoring the calcium ion concentration back to its baseline level, allowing the muscle to relax and prepare for the next contraction.
What would happen to a resting membrane potential if the concentration of a large intracellular anions that are unable to cross the membrane experimentally is increased?
If the concentration of large intracellular anions..i.e. proteins, which are unable to cross the membrane due to their large size.. were to increase, the resting potential would reach a more negative state, a deviation from -70mV to a more negative value do to these anions.
