The sodium potassium pump is a form of active transport in which sodium and potassium end up switching places (one into the cell and one leaves the cell). The pump is located in the cell membrane.

Controls the movement of molecules into and out of the cell?
To put it simply, it is the cell membrane. You can have transport vesicles ect, but the cell membrane is the main barrier between inside and outside. It contains pumps, channels and proteins that are in charge of communication and also control movement of everything from inside and outside. hhh
What are channels in the pumps in the cell membrane mad of?
These are proteins. Transmembrane proteins span the entire membrane.
What structure controls the passage of substances into and out of the cell?
cell membrane
Where is the cell control center and the cell membrane?
where is the cell control membrane and the cell membrane
What Controls what moves in and out of the cell?
Cell membrane
What is cell membrane pumps?
cell membrane pumps use energy to force molecules in a direction opposite of natural.
What are the channels and pumps of the cell membrane made up of?
They are proteinacious .
What substances are used as pumps and channels in the cell membrane?
There is one substance that is used to pump and channel a cell membrane. The substance is known as energy.

What is called membrane pumps?
well membrane pumps obviously
What are channels in the pumps in the cell membrane mad of?
These are proteins. Transmembrane proteins span the entire membrane.
When a vesicle fuses with the cell membrane to get rid of a particle what happens?
a vesicle does not fuse with the cell membrane. The cell membrane goes through endo- or exocytosis to absorb or eject a substance. In this case, exocytosis occurs, so the cell membrane engulfs the particle, pumps it through the membrane with the help of transport proteins, and then the vesicle breaks off and is gone.
What are the special structures in the cell membrane that allow materials such as water and sugar through made of?
PROTEIN!!!!!!!!!!!!!!!!!!!!!!!!!
Why is the cell membrane in a animal cell good at its job?
An animal call membrane is semipermeable (also selectively permeable). This means that it allows the cell to absorb what it needs, get rid of waste or other products, and still keeps the cell enclosed and safe. The membrane can accomplish all these tasks due to the phospholipid bilayer, diffusion, and pumps.
Facilitated diffusion carrier proteins and cell membrane pumps both?
They both transport substances up their concentration gradients.
Why is the sodium-potassium pump called an electrogenic pump?
pumps unequal quantities of Na+ and K+ across the membrane, 3Na+ out of and 2 K+ into the cell per pump cycle. In other words, it generates electricity by producing a net movement of positive charge out of a cell.
Why are carrier proteins in the cell membrane that are used for active transport called ''pumps''?
Because they remove or bring in a chemical against the gradient.
