Does altering the permeability of the membrane change the equilibrium concentration of the solute in the cell?
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.
Explain the results you obtained Include the concentration differences and membrane pore size in your discussion?
The results showed higher concentrations of solute on one side of the membrane compared to the other, indicating a concentration difference. The size of the membrane pores likely influenced the movement of solutes, with smaller pores restricting the passage of larger molecules. This led to selective permeability, allowing only certain molecules to pass through based on their size and concentration gradient.
What is the ability of a cell membrane to allow material to pass through it called?
permeability
The movement of electrons down a concentration gradient via electron transport membrane is used to generate what?
ATP.
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
Does altering the permeability of the membrane change the equilibrium concentration of the solute in the cell?
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.
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 feature of a membrane describes whether molecules can cross the membrane?
permeabiity
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.
What is the difference between diffusion potential and nernst potential?
The Diffusion Potential is the potential difference across the boundary b/w two electrolytic solutions of different compositions The Nernst Potential is the diffusion potential across a membrane that exactly opposes the net diffusion of a particular ion through the membrane
What factor affect osmosis?
Factors that affect osmosis include concentration gradient, pressure, temperature, and permeability of the membrane. Osmosis is the movement of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

What term describes the difference in the concentration of a substance across a cell membrane?
concentration gradient
What regulates the rate of passive transport?
The rate of passive transport is regulated by factors such as the concentration gradient of the solute across the membrane, the surface area available for transport, the permeability of the membrane to the solute, and the temperature of the system. These factors affect the movement of molecules across the membrane without the use of energy.
What is the ability of a cell membrane to allow material to pass through it called?
permeability
What does permeability depend on?
Permeability depends on membrane solubility and the presence of specific integral transport proteins. Other factors such as pressure, concentration, and temperature of the molecules or solutes on either side, as well as the size of the molecules can also affect permeability.
