What else can I help you with?
In an isotonic environment would there be an equal movement of water across the cell membrane?
There would be no net movement of water across the membrane because the amount of solute inside and outside of the membrane is equal.
How does the Concentration gradient of a substance affect the movement of that substance and the expenditure of energy?
A concentration gradient of a substance drives the movement of that substance from an area of high concentration to an area of low concentration. The steeper the concentration gradient, the faster the movement of the substance, requiring less energy to transport it. If the concentration on both sides of the gradient is equal, there is no net movement of the substance.
Why does the level of a more concentrated solution rise when two solutions of different concentrations are separated by a semipermeable membrane and when does it stop rising?
The more concentrated solution is hypertonic and osmotic pressure (a hydrostatic force whose sole purpose in life is to make concentrations equal) tends to move solvent into the more concentrated solution. It will stop rising when either a) the solution concentrations are the same on both sides of the membrane, or b) when the osmotic pressure becomes equal to the ambient air pressure.
How does osmosis explain the movement of water across cell membranes?
Osmosis is the movement of water from a solution of high concentration to a solution of lower concentration through a membrane. Water passes through the membrane, diluting the solution of higher concentration on the other side, until both solutions on either side of the membrane have equal concentrations.
When two solvents are separated by a semipermeable membrane water flows from low solute concentrations to high solute concentrations. What would happen if external pressure is applied to the solution?
"Water ALWAYS follows the salt" or to put it another way, it will try to make the two sides have equal amounts of water. The water will go where there are more solute particles. Water easily passes from one side to the other by simple osmosis.
Water molecules will no longer pass through the semipermeable membrane once equilibrium is reached true or false?
False. There will still be movement of water molecules across the membrane, but there will be no net movement. This means that the number of molecules coming into the cell will equal that going out, and equilibrium will therefore be maintained.
Is it true that once equilibrium is reached roughly equal numbers of molecules move in either direction across a semipermeable membrane?
Yes, once equilibrium is reached, the number of molecules moving in either direction across a semipermeable membrane will be roughly equal. This is because at equilibrium, the concentration of molecules is the same on both sides of the membrane, resulting in an equal likelihood of molecules moving in either direction to maintain balance.
How does water move in osmosis?
Osmosis moves a solvent (eg water) to balance the concentrations of solute either side of a semipermeable membrane. The solvent is not lost.If the concentration of a solution is higher on one side of the membrane than the other, then the water moves across the membrane from the less concentrated side to the more concentrated side to dilute it until the concentrations on either side are equal.
In an isotonic environment would there be an equal movement of water across the cell membrane?
There would be no net movement of water across the membrane because the amount of solute inside and outside of the membrane is equal.
where does osmosis move water from when water is lost but electrolytes are retained?
Osmosis moves a solvent (eg water) to balance the concentrations of solute either side of a semipermeable membrane. The solvent is not lost.If the concentration of a solution is higher on one side of the membrane than the other, then the water moves across the membrane from the less concentrated side to the more concentrated side to dilute it until the concentrations on either side are equal..
What is osmotic?
Osmotic refers to the process of movement of water through a semipermeable membrane from a region of low solute concentration to a region of high solute concentration. This movement continues until there is an equal concentration of solute on both sides of the membrane. Osmosis is important in maintaining the balance of fluids in living organisms.
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
What is osmotic equilibrium?
Osmotic equilibrium refers to the state where there is no net movement of water across a semipermeable membrane due to an equal concentration of solute on both sides. This balance prevents further water flow and maintains stability in the system.
When does the net movement of osmosis stop?
The net movement of osmosis stops when the concentration of solute is equal on both sides of the membrane, resulting in equilibrium. At equilibrium, there is no further movement of water molecules across the membrane.
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.
How does the Concentration gradient of a substance affect the movement of that substance and the expenditure of energy?
A concentration gradient of a substance drives the movement of that substance from an area of high concentration to an area of low concentration. The steeper the concentration gradient, the faster the movement of the substance, requiring less energy to transport it. If the concentration on both sides of the gradient is equal, there is no net movement of the substance.
Why does the level of a more concentrated solution rise when two solutions of different concentrations are separated by a semipermeable membrane and when does it stop rising?
The more concentrated solution is hypertonic and osmotic pressure (a hydrostatic force whose sole purpose in life is to make concentrations equal) tends to move solvent into the more concentrated solution. It will stop rising when either a) the solution concentrations are the same on both sides of the membrane, or b) when the osmotic pressure becomes equal to the ambient air pressure.
