Peptide and hydrogen bonds present in the Primary structure of protein are due to:
Correct answer: D. None of these
- A. Primary and alpha helix structure respectively
- B. Primary and Beta-pleated sheet structures respectively
- C. Secondary and alpha helix structure respectively
- D. None of these
Explanation
Peptide bonds are found in the primary structure, and hydrogen bonds stabilize the secondary structure, including both alpha helices and beta-pleated sheets. Since none of the other options correctly account for both peptide and hydrogen bonds in their correct structural contexts, this is the correct choice.

About Macromolecules
Proteins are classified by shape, composition and structure, from primary amino acid sequence to secondary, tertiary and quaternary organisation, and their biological roles are linked to this structure. Enzymes are examined as protein biocatalysts, including active sites, substrate specificity, activation energy, cofactors and factors affecting activity.
