Read the passage given below and answer the following questions:

When a protein in its native form, is subjected to physical changes like change in temperature or chemical changes like change in pH, the hydrogen bonds are disturbed. Due to this, globules unfold and helix get uncoiled and protein loses its biological activity. This is called denaturation of protein.
The denaturation causes change in secondary and tertiary structures but primary structures remains intact.
Examples of denaturation of protein are coagulation of egg white on boiling, curding of milk, formation of cheese when an acid is added to milk.

Q. α-helix and β-pleated structures of proteins are classified as
  • a)
    primary structure
  • b)
    secondary structures
  • c)
    tertiary structure
  • d)
    quaternary structure
Correct answer is option 'B'. Can you explain this answer?
