Question

39. Albumin is a large protein which circulates freely in human irculates freely in human plasma. Aquaporins act as a channel for water to enter and exit a cell and are located within the lipid bilayer of the cell membrane Based on their physiological locations, how would the tertiary structure of these two proteins mostly likely compare? A. Albumin has a nonpolar core with a polar outer layer, while aquaporins have a polar core with a norpolar outer layer B. Albumin has a polar core with a nonpolar outer layer, while aquaporins have a nonpolar core with a polar outer layer C. Albumin has a nonpolar core with a nonpolar outer layer, while aquaporins have a polar core with a polar outer layer D. Albumin has a polar core with a polar outer layer, while aquaponins have a nonpolar core with a nonpolar Outer layer 40. The primary structure of a protein is primarily maintained by A. peptide bonds B. hydrogen bonds C. ionic bonds D. disulfide bonds E. hydrophobic bonds
please help!

Answer 1

Answer is A

Albumins have polar outer layer with nonpolar core while aquaporins have polar core with non polar outer layer.

Albumins have polar outer layer because of which it is solution in water, thus in plasma of blood. It has nonpolar core which provide lipid molecules such as hormones to be bind and transport which otherwise is not possible ebcause these are nonpolar compounds.

Similarly aquaporins are nonpolar on outside which allows it to be in lipid bilayer while having polar core which allows free movement of water molecules.
