Why do you use dialysis tubing as a model for a cell membrane?
Dialysis tubing is often used to model a cell membrane because it is also a semi-permeable membrane. This means that it only allows certain substances through, not all.
How do solute molecules pass through the membrane?
The solute molecule, when passing through the membrane passively using a carrier protein, is called the substrate. The solute, or substrate will bind to the carrier protein from the outside, the carrier protein changes conformation, and the substrate is exposed to the inside of the membrane.
What is the substance being dissolved into a solvent?
The substance dissolved in a liquid is called the solute.
What is a substance called that is dissloved in a solution?
The substance is dissolved into a solution is called the "solute."
A substance that is dissolved in liquid is a what?
The dissolved substance is a called a solute.
Whats the only substance that carries out osmosis?
The only substance that carries out osmosis is water. Osmosis is the movement of water through a semi-permeable membrane from a low concentration of solute to a high concentration of solute in the pursuit of equilibrium across the membrane.
What best describes a cell that is isotonic for a substance?
The solute concentration is equal on both sides of the cell membrane
What is the difference between facilitates diffusion and solute pumping?
Facilitated diffusion is an example of passive transport, while solute pumping is an example of active transport. This means that facilitated diffusion does not require the use of energy, while solute pumping does. Sometimes, certain particles are either too big or lipid insoulble to pass through the cell membrane. Therefore, they need a protein carrier which acts like a tunnel. This allows these particles to pass through the cell membrane. However, solute pumping is when amino acids, some sugars, and ions are transported b solute pumps. Also, ATP energizes during solute pumping. Facilitated diffusion is an example of passive transport, while solute pumping is an example of active transport.

What sentence best describes a cell that is isotonic for a substance?
The solute concentration is equal on both sides of the cell membrane.
What is the substance that dissolves in a solute?
The substance that dissolves is called the "solute" and the substance that the solute dissolves in is called the "solvent".
What is the movement of water through a selectively permeable membrane?
The movement of water through a selectively permeable membrane is called diffusion. Water will always diffuse down a concentration gradient, from high solute concentration to low solute concentration.
How do solute molecules pass through the membrane?
The solute molecule, when passing through the membrane passively using a carrier protein, is called the substrate. The solute, or substrate will bind to the carrier protein from the outside, the carrier protein changes conformation, and the substrate is exposed to the inside of the membrane.
A substance that dissolves another substance?
A solute can dissolve in another substance. The substance that does the dissolving is called the solvent.
What is the of definition omasis and an exsample?
movement of a solvent (as water) through a semipermeable membrane (as a living cell) into a solution of higher solute concentration that tends to equilize the concentration of solute on the two sides of the membrane.
How does osmosis happen?
Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane
Where and when does osmosis occur?
Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane .
