Explanation / Answer

22) the alpha-helix and beta pleated sheets are examples of SECONDARY structure of proteins.

Reason: This is formed when two sequences of amino acids ( peptide chains) interact with each other. Hence, as it the inter-sequential interactions, they are secondary in nature.

Have a nice day!
