When the molecules on both sides of a cell membrane are in equilibrium what will the molecules do?
If the concentration of molecules on both sides of a membrane is the same, nothing will happen to the molecules. Osmosis only occurs when there is an imbalance of the molecules across the cell membrane.
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.
If the concentrationof molecules on both sides of a membrane is the same the molecules will?
When the concentration of molecules on both sides of a semi permeable membrane are the same, there is no concentration gradient. Therefore, the system is at a state of equilibrium and the molecules remain static
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 is it possible for some molecules to be at equilibrium across a biological membrane and yet not be at the same concentration on both sides?
The equilibrium distribution of a molecule across a membrane depends on concentration and membrane potential. A charged molecule will respond to both components of the electrochemical gradient and will distribute accordingly. K+ ions for example, are at equilibrium across the plasma membrane even though they are 30-fold more concentrated inside the cell. the difference in concentration is balanced by the membrane potential, which is more negative on the inside. The membrane potential opposes the movement of cations to the outside of the cell.

Diffusion stops when molecules reach the?
When molecules reach equilibrium, diffusion stops. This occurs when there is an equal concentration of molecules on both sides of the membrane and no net movement.
What is diffusion be able to tell which direction molecules will diffuse?
Diffusion is the process by which something dissolved in a fluid will move from higher concentrations to lower concentrations. A drop of food coloring in a glass of water will gradually diffuse throughout the entire glass until it is a uniform color. In biology, diffusion is commonly across a membrane (like a cell membrane). If the concentration of sodium is higher on one side of a membrane, and it can pass through the membrane, it will move from the higher concentration to the lower until the two sides have the equal concentration.
According to the rules of osmosis a system will reach a state of equilibrium when there are equal numbers of molecules on both sides of a water-permeable membrane.?
Osmosis involves the movement of water molecules across a semi-permeable membrane from an area of higher concentration to an area of lower concentration. Equilibrium is reached when the concentration of water is the same on both sides of the membrane.
What happens to a higher concentration of dissolved molecules on one side of a cell membrane during the process of diffusion?
the side of the cell membrane with the higher molecule concentration moves molecules to areas of lower concentration during diffusion until an equilibrium is reached between both sides of the membrane.
In general the net movement of small uncharged atoms and molecules through the membrane of a cell will occur until?
Molecules will move into or out of the cell until it becomes isotonic to its surroundings. This means that the concentration of the molecules inside the cell is equal to the concentration of the molecules outside the cell.
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 diffusion react when the concentration is the same on both sides?
When the concentration is the same on both sides, diffusion will reach equilibrium, meaning that there will be no net movement of molecules across the membrane. At this point, the concentration of molecules will be equal on both sides and diffusion will cease.
