What type of proteins don't go through the bilayer?
It important that some proteins extend all the way through the bilayer of a plasma membrane. This is to offer protection to the cell and also facilitate the transport of various substances in and out of the cell.
Membrane pores consist of what chemically?
Membrane pores consist of proteins, specifically transmembrane proteins such as ion channels or porins. These proteins create passageways through the lipid bilayer of the membrane, allowing for the selective transport of ions or molecules across the membrane.
What membrane proteins are integral proteins?
Integral membrane proteins include transmembrane proteins, which span the entire lipid bilayer, and lipid-anchored proteins, which are attached to the membrane through lipid molecules. These proteins are essential for various cellular functions such as cell signaling, transport, and structural support. Examples include ion channels, transporter proteins, and receptors.
What Proteins that penetrate both layers of the phospholipid membrane?
Transmembrane proteins are proteins that span both layers of the phospholipid bilayer. These proteins have regions that interact with the hydrophobic core of the membrane, allowing them to pass through and interact with both the inner and outer environments of the cell. Examples include ion channels and transporters.
Are transmembrane proteins inserted into the membrane as they are made or after they are made?
http://pathmicro.med.sc.edu/mhunt/RNA-HO.htm Transmembrane proteins are made on ribosomes bound to the endoplasmic reticulum. They are inserted into the endoplasmic reticulum membrane as they are made, glycosylated in the endoplasmic reticulum and pass through the Golgi body where substantial modification of the carbohydrate chains occurs. They are then transported, in vesicles, to the appropriate cell membrane; in the case of vesicular stomatitis virus, this is the plasma membrane ( hope it helps this is what i wrote on my worksheet ) gook luck!! kadie :-)

What are proteins that stick into the cell membrane and pass all the way through called?
carbohydrate molecules ( they are attached to most of these proteins.)
Is a protein that forms an ion channel through a membrane is most likely to be a peripheral protein a trans membrane protein a phospholipid an enzyme or an entirely outside the phospholipid?
A protein that forms an ion channel through a membrane is most likely to be a transmembrane protein. Transmembrane proteins span the lipid bilayer, allowing them to create channels for ions to pass through the membrane. Peripheral proteins are typically found on the surface of the membrane and do not form channels.

Membrane pores consist of proteins, specifically transmembrane proteins such as ion channels or porins. These proteins create passageways through the lipid bilayer of the membrane, allowing for the selective transport of ions or molecules across the membrane.
What is a holes in plasma membrane through which molecules pass across capillary wall?
The plasma membrane is made up of a lipid bilayer and some proteins. The transmembrane proteins are the structures which are involved in the transport of molecules in or through the cell.

Are transmembrane proteins amphipathic?
yes, transmembrane proteins have both polar and non-polar regions. This is because these proteins are dispersed through the membrane almost like pieces of stones. So, to be inside the hydrophobic region of the phospholipid bi-layer AND also outside of it in the water or aqueous solution they transmembrane protein needs to be amphipathic.
What is the function of the anchored proteins?
Anchored proteins are proteins that are attached to a cell membrane through lipid modifications or transmembrane domains. They play important roles in cell signaling, cell adhesion, and maintaining cell structure. By being anchored to the membrane, these proteins are able to interact with other molecules outside and inside the cell.
What are the channels in the cell membrane made of?
The channels in the cell membrane are typically made of proteins that form a pore-like structure spanning the lipid bilayer. These channel proteins allow specific ions or molecules to pass through the membrane, regulating the movement of substances in and out of the cell. The structure of these channels can vary, influencing their selectivity and function.
What is the function of the integral proteins?
Some integral proteins form "channels" or "pores". These channels are responsible for allowing specific types of ions to move through the cell membrane to go from the extracellular fluid to the cytosol of the internal side of the cell.
