Which type of protein plays an important role in transmitting signals in the nervous system?
ion channel membrane proteins
What type of membrane is membrane plasma?
The plasma membrane is referred to as a biological membrane or bio-membrane.Briefly, the plasma membrane may also be generally referred to as cell membrane.
This type of membrane lines a body cavity that does NOT open directly to the outside?
Serous membraneA serous membrane also called the serosa is the type of membrane that lines cavities that do not open to the outside of the body.
What does captha mean and how do you get rid of it?
It's where you type in the letters in the distorted picture. Computers can't usually read the distorted image. This is a security measure, so the only way to get rid of it is to enter the letters in the picture.
What proteins act like selective passageways in the cell membrane?
The lipid bilayer is a tightly packed membrane of hydrophobic (dont like water) molecules, so only hydrophobic or very very small molecules can go directly through it. Large molecules such as hormones need to have a special hole in the membrane that they can fit through, but some are so large that if the membrane created a plain old hole, everything would be able to fit through, even things the cell doesnt want. The proteins create special openings that allow only a specific variety of molcule to go through, like only a special type of hormone. They work a lot like a lock and key, so when the molecule encounters its protein, it acts like a key and opens the portal. once the molecule passes, the protein closes the opening and nothing else can go through.
What type of channel on the postsynaptic membrane binds neurotransmitter?
a chemically gated channel
What do the channel proteins in the cell membrane do?
Channel proteins, a type of transport proteins to the cells, move molecules from outside of the membrane to the inside
What type of channel does sodium and potassium use to diffuse across the plasma membrane of all cells?
voltage type of channel
What is the purpose of the embedded proteins in the membrane?
There are generally channels which allow nutrients and other materials in or out of the cell. What goes in and out of the channel depends on the channel type.
Which type of protein plays an important role in transmitting signals in the nervous system?
ion channel membrane proteins
What is the function Protein embedded in cell membrane?
There are generally channels which allow nutrients and other materials in or out of the cell. What goes in and out of the channel depends on the channel type.
Binding of a signaling molecule to which type of receptor leads directly to a change in the distribution of ions on opposite sides of the membrane?
Ligand-gated ion channel
Binding of a signaling molecule to which type of receptor leads directly to a change in distribution of ions on opposite sides of the membrane?
ligand gated ion channel
What will occur when an excitatory postsynaptic potential EPSP is being generated on the dendritic membrane?
A single type of channel will open, permitting simultaneous flow of sodium and potassium.
What is meant by membrane is membrane in cell function?
membrane, is a type of brain that function to think what to do.
What is the eukaryote of a membrane?
a eukaryote is a type of cell not part of a membrane!
What type of membrane is required for osmosis?
A selectively permeable membrane
