Yes, altering the permeability of the membrane can change the equilibrium concentration of the solute in the cell. By adjusting how easily the solute can pass through the membrane, you can affect the balance between the concentration of the solute inside and outside of the cell, ultimately impacting the equilibrium concentration.

Does increasing membrane permeability affect the time it takes for the osmometer to reach equilibrium?
Yes, increasing membrane permeability can affect the time it takes for the osmometer to reach equilibrium. Higher permeability allows for faster movement of solvent and solutes across the membrane, which can result in a quicker establishment of equilibrium between the two solutions.
Why resting membrane potential value sodium is closer to equilibrium of potassium?
The resting membrane potential value for sodium is closer to the equilibrium of potassium because the sodium-potassium pump actively maintains a higher concentration of potassium inside the cell and a higher concentration of sodium outside the cell. This leads to a higher permeability of potassium ions at rest, resulting in the resting membrane potential being closer to the equilibrium potential of potassium.
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?
The difference in concentration of K+ and Na+ across the plasma membrane, along with the membrane's permeability to these ions, generates the resting membrane potential. This potential is essential for maintaining electrical excitability in cells, such as neurons and muscle cells, and is involved in processes like nerve signaling and muscle contraction.
Is diffusive equilibrium possible for the molecule that is impermeable?
No, diffusive equilibrium requires a concentration gradient and the ability of the molecule to pass through a membrane. If a molecule is impermeable, it cannot move freely across the membrane, so diffusive equilibrium is not possible for that molecule.
How does temperature affect permeability?
Temperature can affect permeability by changing the viscosity of the solvent, altering the diffusion rate of solutes through the membrane. Higher temperatures generally increase permeability as molecules have more kinetic energy to move through the membrane. However, extreme temperatures can denature proteins in the membrane and reduce permeability.

When the concentration of molecules on both sides of a membrane is the same (equilibrium) the molecules will?
reach dynamic equilibrium. Answer : move across the membrane in both directions (equilibrium).
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 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
When the concentration of molecules on both sides of the membrane is the same the molecules will?
reach dynamic equilibrium. Answer : move across the membrane in both directions (equilibrium).
What feature of a membrane describes whether molecules can cross the membrane?
permeabiity
How is equilibrium related to diffusion and osmosis?
Equilibrium in diffusion and osmosis is reached when there is a balanced distribution of particles or solutes across a membrane, resulting in no net movement of particles. In diffusion, equilibrium is reached when there is an equal concentration of particles on both sides of the membrane. In osmosis, equilibrium is reached when the water concentration is the same on both sides of the membrane.
What can differential permeability also be described as?
Differential permeability can be described as phenomenon where a differential permeable membrane through different diffusion processes allows smaller molecules/ions as glucose, sodium and chlorine to diffuse out while macromolecules as starch to remain behind until an equilibrium is reached, where concentration of smaller molecules/ions equals on both sides of the differential membrane.Differential permeability can also be described as Dialysis.
What is the equilibrium of solute across a membrane?
The equilibrium of solute across a membrane is reached when the concentration of the solute is the same on both sides of the membrane. This means that the movement of the solute molecules is balanced, with an equal number of molecules moving in and out of the membrane. At equilibrium, there is no net movement of solute across the membrane.
What is the difference between diffusion potential and nernst potential?
Diffusion potential arises due to concentration differences of ions across a membrane without considering membrane permeability. Nernst potential, on the other hand, takes into account both concentration differences and membrane permeability for a specific ion to calculate the equilibrium potential at which the net flow of that ion is zero.
What is osmosis controlled by?
Osmosis is primarily controlled by the concentration gradient of solute particles across a selectively permeable membrane. Water will move from an area of low solute concentration to an area of high solute concentration in an attempt to equalize the concentrations on both sides of the membrane.
