Peripheral proteins typically contain substantial sections of _________ which is/are __________ and therefore can interact with the ________ sections of the lipid bilayer.

Solution

Peripheral proteins have charged, polar amino acids. Through which they interact with the environment . Charged hydrophilic amino acid residues can easily interact with the environment. So here the first option is correct. I.e. Peripheral proteins typically contain substantial sections of charged amino acids which are polar and therefore can interact with the exterior section of lipid bilayer.
