The hydrophilic regions of a membrane protein are most likely to be found?
Wiki User
∙ 15y ago
The hydrophilic regions of a transmembrane protein are likely to be found on the exterior of the membrane. The transmembrane protein may have three parts: a hydrophilic segment, a hydrophobic segment, and another hydrophilic segment. The hydrophobic region would be in between the hydrophilic regions. The hydrophobic region will be embedded in the membrane and the hydrophilic regions will be on the inside and outside of the membrane.

What is this statement most likely referring to Small nonpolar molecules may pass through this structure but others require a protein channel?
Small non-polar molecules may pass through a a semipermeable membrane but others require a protein channel.

Are volcanic mudflows especially likely in dry regions?
No, volcanic mudflows are especially likely in wet regions
How does the shape of a molecule affect it's polarity?
The shape of a molecule affects its polarity by determining the spatial arrangement of its polar bonds. If a molecule is symmetrical, with polar bonds arranged symmetrically, it will likely be nonpolar overall. However, if the molecule is asymmetrical, with polar bonds arranged asymmetrically, it will likely be polar overall. The polarity arises due to the unevenly distributed electron density caused by the electronegativity difference between the bonded atoms.
Where in the membrane does facilitated diffusion occur?
Diffusion will most likely to occur where there is a high concentration of gas or water then the particles distibute evenly to the area of low concentration. for example if you could smell a turkey cooking in the oven from upstairs without anyone telling you.
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.
Is trp or gln more likely on a protein surfaces?
gln is more likely to be on the surface of protein because this is hydrophilic and can make interaction with water. However, trp is hydrophobic and want to avoid any contact with water so therefore buried in the interior of protein
The r group or side chain of the amino acid serine is -ch2-oh the r group or side chain of the amino acid alanine is -ch3 where would you expect to find these amino acids in a globular protein in aq?
Serine, being hydrophilic, will be more likely to appear near the surface of a globular protein in solution, and alanine, being hydrophobic, will more likely appear near the centre of the protein. This illustrates the "hydrophobic effect", which is one of the effects that stabilizes the tertiary and quaternary structures of proteins. The hydrophobic effect is not due to an intramolecular force but the tendency of hydrophilic and hydrophobic amino acids to interact oppositely with water and segregate into surface and inner regions.
What amino acids would be most likely found buried deep within the interior of a protein?
The lipophilic (or hydrophobic) ones are slightly more likely to hold interior positions than the hydrophilic ones.

What three factors will determine whether a molecule will diffuse into a cell?
A molecules ability to travel across a cell membrane depends on, among other things; 1. The concentration of the molecule inside and outside of the cell (molecules may travel against the concentration gradient using protein pumps at the cost of ATP). 2. The size of the molecule (large molecules are less likely to pass). 3. The polarity of the molecule (charged molecules have a more difficult time crossing the cell membrane).
Which structure is the statement below most likely referring to Small nonpolar molecules may pass through this structure but others require a protein channel.?
Small non-polar molecules may pass through a a semipermeable membrane but others require a protein channel.
Water molecules diffuse through a selectively permeable membrane?
Water diffuses by facilitated diffusion, passing through water permeable protein channels embedded in the cell membrane. Water molecules can not pass through the lipid bilayer because water is polar. However, polar molecules pass though the cell membrane through the protein channels. The proteins that aid water in passing through the cell membrane are called aquaporins. "Aqua" for water, and "porin" for pore. A "water pore" in essence.
What would a synovial membrane most likely be found in?
A synovial membrane is most likely to be found in the joint cavity.
