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.


How do carrier proteins facilitate the passive transport of molecules across a membrane?

Carrier proteins facilitate the passive transport of molecules across a membrane by binding to specific molecules on one side of the membrane and changing shape to transport the molecules across to the other side. This process does not require energy and is driven by the concentration gradient of the molecules.


How do larger molecules move across epithelial membranes in the capillaries?

Larger molecules can cross epithelial membranes in capillaries through processes like transcytosis, where the molecule is taken up by the cell on one side and transported across the cell to be released on the other side. This process often involves vesicles that transport the molecule across the cell.


What part of the cell membrane attracts water molecules?

The hydrophilic heads of phospholipids in the cell membrane attract water molecules. These heads have a charge that interacts with the polar water molecules, allowing them to form hydrogen bonds with the water. This hydrophilic property helps create a stable structure for the cell membrane.


When will water and solutes stop moving across a membrane?

Particles in a given medium stop moving across the membrane during diffusion when a state of equilibrium is reached, that is when the number of particles on either side of the membrane equalizes.

What is the diffusion of water molecule through a selectively permeable membrane?

It's called osmosis. A selectively permeable membrane will only allow certain molecules to pass trough. To illustrate: If you have a high concentration of sugar molecules on one side of the membrane, no sugar on the other side, and the sugar molecules are too big to pass trough the membrane. If this is the case, then water molecules will diffuse over to the side of the membrane with a high sugar concentration. This happens because the molecules try to distribute themselves evenly in the solution. The water molecules move because the sugar molecules can't.


Why did the number of the water molecules on each side of the membrane change where as the number of sugar molecules stayed the same?

The membrane is permeable to water but not to sugar.

What are the benefits of reverse osmosis systems in purifying water?

Reverse osmosis is a membrane technical filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane.


Why doesn't powder charcoal filter through a membrane?

Powdered charcoal particles are too large to pass through the pores of a membrane due to their size. The membrane acts as a barrier that only allows smaller molecules or particles to pass through, thus retaining the charcoal particles on one side of the membrane.


What is the model to describe the side to side movement of many different molecules in a cell membrane?

The model that describes the side-to-side movement of various molecules within a cell membrane is the Fluid Mosaic Model. This model depicts the cell membrane as a flexible, dynamic structure composed of a phospholipid bilayer with embedded proteins, cholesterol, and carbohydrates. The lipid molecules can move laterally, allowing for the fluidity and diversity of interactions among membrane components, which facilitates various cellular functions.


What is it called when the concentration of water molecules is the same on each side of the cell membrane?
