Question

Later the host says that channel proteins will allow polar molecules across the membrane by creating a hydrophilic passage. This is TRUE. a. What types of amino acid R groups do you think will line the channel protein interior?b. What types of interactions can the polar compound have with the interior of this passage way (channel protein)? c. Are these the same interactions that this polar compound can have on the outside of the membrane with water? [Select]

Answer 1

Answer:

Channel proteins:

On the basic level of the cellular structures we can analyze the different proteins channels through which the different molecules are moved across the membrane by the basic concept of the passive diffusion.  As for the transportation of the materials there is no extra energy required to carry out the process. While it merely depends upon the concentration of molecules on each side of the cell membrane.

A- Types of amino acids R groups: The non-polar amino acids which can form the bonding with the hydrophobic tails of the phospholipids inside the cell membrane structures are present on the interior side of the system. They have the basic function of transportation of the materials across the membrane by the phenomenon of passive diffusion. As the R groups is found inside the amino acid glycine. While some of the non-polar amino acids are valine, methionine, and alanine etc.

B.Interaction of amino acids in the interior of cell membrane:

There some non-polar amino acids that are found in the interior side of the cell membrane, as it operates for the facilitation of the materials transportation across the cell membrane, by the formation of bonds with the hydrophobic tails of the phospholipids.

C.Polar amino acids on the outside of the cell membrane: In order to facilitate the transportation of the molecules or materials across the cell membrane, there are some polar amino acids which forms the bonds with the hydrophillic side or head of the phospholipid molecules, leading to make more efficient in nature and enhance the capacity of the cell wall to continue the formation of the channels all across its structure.
