A. Consumer all the other ones don't make sense
The types of amino acid r groups will line the channel protein interior would be non-polar.
On the interior side of the system, there are non-polar amino acids that can form bonds with the hydrophobic tails of phospholipids inside cell membrane structures. By using the phenomenon of passive diffusion, they perform the fundamental task of moving materials across the membrane. The amino acid glycine contains an R group, as is the case. Valine, methionine, and alanine are a few of the non-polar amino acids, as are others.
Amino groups are more prevalent than carboxylic groups in polar amino acids with a positive charge. A more basic amino acid then results. On the "R" group of these amino acids, there is a positive charge. Lysine, arginine, and histidine are some examples of compounds that fall under this category.
