27. The given structure is the sequence of amino acids. Amino
acids are linked with each other by peptide or amide or CO-NH
bond.
So, in order to release the monomers or amino acids, the CO-NH bond
has to be broken down by hydrolysis, i.e., bond D has to be broken
down by hydrolysis to release the monomers or amino acids.
Hence, option "d" is the correct answer.
28. An amino acid can be classified mostly by the side chains of
its variable group or "R" group.
Hence, option "e" is the correct answer.
29. proteins have two types of secondary structures. They are
alpha helices and beta pleated sheets. These structures are
stabilized by hydrogen bonds.
Hence, option "e" is the correct answer.
30. peptide bond is formed between the carboxyl group of one
molecule and the amino group of another molecule.
Hence, option "a" is the correct answer.
