What is an impermeable solute?
An impermeable solute is a substance that cannot pass through a semipermeable membrane, such as a cell membrane. This means that the solute is unable to diffuse or move across the membrane and remains on one side of the membrane.
What type of channel does sodium and potassium use to diffuse across the plasma membrane of all cells?
Sodium and potassium diffuse across the plasma membrane of cells through ion channels called voltage-gated channels. These channels open and close in response to changes in membrane potential, allowing sodium and potassium ions to flow down their electrochemical gradients.
How does diffusion occur through a semipermeable membrane?
Diffusion through a semipermeable membrane occurs when molecules move from an area of high concentration to an area of low concentration, passing through the membrane. This process is driven by the natural tendency of molecules to spread out and reach equilibrium. The semipermeable membrane allows only certain molecules to pass through based on their size and charge, regulating the movement of substances across the membrane.
In the process known as osmosis what moves through a semipermeable membrane into an area of concentration?
In osmosis, water molecules move through a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration, in order to equalize the solute concentration on both sides of the membrane.
Can osmosis occurs only in liquids?
No, osmosis can also occur across a semipermeable membrane between a liquid and a gas. For example, water vapor can move through a semipermeable membrane to equalize the concentration on either side.
What structure does oxygen diffuse through that a sodium ion may need active transport?
A semipermeable membrane

The statement below refers to a structure of the cell oxygen diffuse through this structure but sodium ion may need active transport which structure is this statement most likely referring to?
a semipermeable membrane
Can ions diffuse through a membrane?
Yes, ions can diffuse through a membrane.
Which substances did not diffuse the membrane?
starch doesnt diffuse through the dialysis membrane.
What moves through a semipermeable membrane into an area of what concentration?
Water moves through a semipermeable membrane from an area of high to low concentration. This is called osmosis.
What type of channel does sodium and potassium use to diffuse across the plasma membrane of all cells?
Sodium and potassium diffuse across the plasma membrane of cells through ion channels called voltage-gated channels. These channels open and close in response to changes in membrane potential, allowing sodium and potassium ions to flow down their electrochemical gradients.
How could you prove or disprove that a specific solute was able to diffuse through w semipermeable membrane?
To prove that a specific solute can diffuse through a semipermeable membrane, you could set up an experiment where the solute is placed on one side of the membrane, and a solution without the solute is on the other side. Over time, you would measure the concentration of the solute on both sides of the membrane. If the concentration increases on the side without the solute, it indicates that diffusion has occurred. To disprove diffusion, you would find that the concentration remains unchanged on the opposing side, suggesting that the solute cannot pass through the membrane.

The rate of diffusion through a semipermeable membrane will be lowest when?
The rate of diffusion through a semipermeable membrane will be lowest when temperatures are low. Lower temperatures decrease the energy of the molecules, which in turn decreases the rate of diffusion.
