Does altering the permeability of the membrane change the equilibrium concentration of the solute in the cell?
yes
Does increasing membrane permeability affect the time it takes for the osmometer to reach equilibrium?
It should. The permeability of a membrane defines how fast substances move across a membrane from a high concentration environment to the lower concentration environment. The more permeable the membrane the sooner equilibrium is reached when the concentrations on both side are the same.
What is the ability of a cell membrane to allow material to pass through it called?
permeability
What has a more vigorous effect on cell membranes acid temperature or alcohol?
Alcohol affects the permeability of the cell membranes. It would have the most vigorous effect.
What effect does the concentration gradient of the interstitial fluid have on the maximum urine concentration?
The urine concentration increased.
Does altering the permeability of the membrane change the equilibrium concentration of the solute in the cell?
yes
What is an example of diffusion in a sentence?
The rate of diffusion is determined by the permeability of the membrane and the concentration gradient.
What is the effect of ADH on the permeability of the wall of the collecting duct?
coolio
What is meant by magnetic permeability?
All materials are magnetized when placed in the magnetic field . The material magnetized by the effect of a magnetic field is called magnetic permeability.
Does increasing membrane permeability affect the time it takes for the osmometer to reach equilibrium?
It should. The permeability of a membrane defines how fast substances move across a membrane from a high concentration environment to the lower concentration environment. The more permeable the membrane the sooner equilibrium is reached when the concentrations on both side are the same.
What feature of a membrane describes whether molecules can cross the membrane?
permeabiity
What is the ability of a cell membrane to allow material to pass through it called?
permeability
What does the difference in the K and Na concentration on either side of the plasma membrane (and permeability of the membrane to those ions) generate?
Resting membrane Potential
What has a more vigorous effect on cell membranes acid temperature or alcohol?
Alcohol affects the permeability of the cell membranes. It would have the most vigorous effect.
What effect does the concentration gradient of the interstitial fluid have on the maximum urine concentration?
The urine concentration increased.
Are the rates of absorption and diffusion constant for all molecules?
no, the rates are different depending on the size of the molecule, the permeability of the membrane, the concentration gradient etc etc.
There is a greater concentration of na plus and there is a greater concentration of k plus in the cell?
There is a greater concentration of Na plus outside and there is a greater concentration of K plus inside the cell. When the stimulus is delivered, the permeability of the membrane is changed, and Na plus diffuses into the cell, initiating the depolarization of the membrane.
