what level of protein structure is controlled by hydrogen bonds between amino acid backbones?
tertiary
quaternary
secondary
primary

Explanation:

The secondary structure of proteins is formed by hydrogen - bonds between the amino - acid backbones. Tertiary structure is due to interactions between side - chains and quaternary structure involves multiple polypeptide chains. The primary structure is the linear sequence of amino acids and is not directly controlled by hydrogen bonds between backbones in the same sense as secondary structure.

Answer:

C. secondary
