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.
What is cell membrane pumps?
cell membrane pumps use energy to force molecules in a direction opposite of natural.
What are membrane channels and pumps made of?
Protiens
Do membrane pumps transport protein?
yes they can
What are the channels and pumps of the cell membrane made up of?
They are proteinacious .
Why is the ATP required for membrane pumps systems to operate?
because it has to
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.
What does aldosterone increase in the basolateral membrane?
Basolateral Na+ K+ ATPase pumps
What are intramembrance pumps?
transport protieins may act as pumps moving ions or small molecules in either direction acroos the plasma membrane
What is the function of proton pumps localized in the plant plasma membrane?
To create a gradient and to charge the membrane so that other processes can take place.
What are channels in the pumps in the cell membrane mad of?
These are proteins. Transmembrane proteins span the entire membrane.
What helps to allow materials to cross the plasma membrane?
Integral proteins - proteins which span the width of the membrane. This can be things such as channels and pumps.
