channel protein definitions
# Definition Sets
1protein that forms a channel to allow a particular molecule or ion to cross the plasma membrane6 sets
2a membrane protein that forms a channel or pore completely through the membrane and that is usually permeable to one or to a few water-soluble molecules, especially ions.3 sets
3an integral protein that selectively allows molecules across the plasma membrane. see also entries under 'ion channel', 'voltage-gated channel', and 'ligand-gated channel'.2 sets
4a membrane protein that forms tunnel-like pores in the cell membrane, allowing electrically charged ions in and out of the cell.2 sets
5has ion channels to move ions in and out of cell2 sets
6lets substances pass through2 sets
7transport protein that functions by having a hydrophilic channel that certain molecules use as a tunnel through the membrane2 sets
8a membrane protein that forms a channel or pore completely throught the membrane and that is usually permeable to one or to a few water-soluble molecules, especially ions1 set
9a protein that molecules or ions can move freely accross, or carriers that selectively combine with an ion or substrance to help it move accross the membrane1 set
10protein responsible for mediating the passive transport of molecules from one side of the lipid bilayer to the other1 set
11pore1 set
12provide corridors that allow a specific molecule pr ion to cross the membrane1 set
13an integral protein that selectively allows molecules across the plasma membrane, by forming tunnel-like pores in the cell membrane, carries out faccilitated diffusion1 set
14integral protein, not a glycoprotein.1 set
15lets stuff get through the cell membrane1 set
16involved in the passage of molecules through the membrane. they have a channel that allows a substance to simply move across the membrane.1 set
17a substance can simply move across the protein1 set
18openings in the cell membrane that allow passage of certain molecules into and out of the cell. doors into building1 set
19protein embedded in the membrane that carries large molecules with or ions against the concentrated gradient1 set
20allows molecules or ions to cross plasma membrane (integral, always open)1 set
21protein embedded in the membrane that carries large molecules with or ions against the concentration gradient.1 set
22a substance, located in the cell membrane and made of amino acids, which other substances can pass through to cross the cell membrane1 set
23an integral protein that permits a certain type of ion to pass through the plasma membrane1 set
24a protein that allows a particular molecule or ion to feely cross the membrane as it enters or leaves the cell1 set
25pore through which a substance can move1 set
26a passive transport protein that forms channels in the lipid bilayer through which certain ions can cross the membrane.1 set
27provides hydrophilic corridors to cross the membrane1 set
28forms a channel to allow a particular molecule or ion to cross the plasma membrane1 set
29a transport protein that functions by having a hydrophobic channel that certain molecules or atomic ions use as a tunnel through the membrane1 set
30membrane-protein with a tunnel like shape that creates a channel through a membrane that allows charged particles (ions) to pass through.1 set
31have hydrophilic channel that certain molecules/atomic ions use as a tunnel through the membrane1 set
32protein that are found in the cell membranes that aid in transporting molecules in and out of the cell1 set
33a protein in the plasma membrane that has a pore through it for the passage of materials between the cytoplasm and extracellular fluid1 set
34helps with diffusion, no shape change1 set
35a protein in the plasma membrane that forms a channel to allow a particular molecule or ion to cross the plasma membrane1 set
36faciliates the rapid transport of water through the plasma membrane in response to osmotic gradients1 set
37allow particle molecules to pass the membrane freely (like tunnels)1 set
38a membrane protein that forms tunnel-like pores in the cell membrane, allowing electricity charged ions in and uot of the cell1 set
39a membrane protein that forms an aqueous passageway through which specific solutes may pass.1 set
40carries out faccilitated diffusion; passes water molecule though a channel or other specific solutes1 set
