Question

decide is each statement is referring to primary, secondary, tertiary, or quaternary structures of proteins:
hydrogen bonds are responsible for the folding in this level of protein structure

Answer 1

The statement "hydrogen bonds are responsible for the folding in this level of protein structure" refers to the **secondary structure** of proteins. In secondary structure, hydrogen bonds form between the backbone atoms in the polypeptide chain, leading to the formation of structures such as alpha-helices and beta-pleated sheets.
