Movement across the cell membrane made possible by a protein embedded in the cell membrane?
It is a selectively permeable membrane that allows certain substances in and out, but keeps harmful substances from entering the cell. It could be compared to the security guard at the door of an airport that makes sure that nobody dangerous gets in or out.
What is the role of transport proteins within the plasma membrane?
The membranes around cells and even around some organelles do not allow much to go in and out. If the substance is too large, it can't move in without help. If the charge is 'incorrect', it needs help as well.
Osmosis is a diffusion process that moves through the membrane from higher to lower concentration. molecules salt water nutrients?
Switch the word "solvent" to "water" and you have the best definition possible.
You can smell a burning scented candle across a room because?
the liquid vaporizes and the resulting gas molecules wander about the room
What happens when two different concentrations of sugar solutions are placed on opposite sides of a selectively permeable membrane in a container?
In this situation, osmosis will occur. This means that there will be a net (average) movement of water particles from the solution with the lowest concentration to the solution with the highest concentration. Remember that although the net movement is in this direction, the water particles move about randomly so some will also go in the other direction. Eventually, The concentrations will equal each other and there will be no net movement. Hope this helps.
What is the diffusion of water across a selectively premeable membrane called?
It is osmosis .
The passive transport of water across a selectively permeable is called?
Osmosis is the movement of water molecules across a selectively permeable membrane.
What can osmosis be described as?
Osmosis is the movement of water molecules across a selectively permeable membrane.
What process require ATP energy to transport materials across a selectively premeable membrane into the cell?
active transport
What is an example for selectively premeable?
The phospholipid bilayer that composes the cell membrane is an example of a selectively permeable membrane. It only lets through small, non-polar molecules.
Diffusion of water molecules across a selectively permeable membrane?
it is osmosis
Is it true if the process by which water moves across a selectively permeable membrane is called diffusion?
Diffusion is a physical process. When it is performed through a selectively permeable membrane, it is called osmosis. Thus osmosis is an appropriate word for movement of water molecules through a selectively permeable membrane and not diffusion.
What process - movement of water across a selectively permeable membrane from an area of high water concentration to an area of low concentration?
Osmosis is the process by which water moves across a selectively permeable membrane.
In osmosis which membrane provides net movement of water without movement of NaCl?
Osmosis across a selectively permeable membrane allows water across but disallows other particles across the membrane.
Diffusion is defined as a movement of molecules?
Is Diffusion the movement of molecules from a greater to a lesser concentration.
Movement of water molecules across the membrane is the result of?
osmosis
How is the function of epithelium reflected in its structure?
Since epithelium needs to serve as both a barrier and selectively permeable membrane, the cells need to be tightly junctioned to one another (thus prohibiting paracellular transport) and need to express channels, transporters or exchangers to allow for movement of selected ions/molecules across the epithelial barrier
