Multiple choice

The functional as well as three dimensional structural differences between two different enzymes are due to

  1. difference in their roles in DNA metabolism

  2. secondary structures

  3. difference in their roles in protein metabolism

  4. amino acid sequences

D Correct answer
Explanation

The amino acid sequence (primary structure) determines how a protein folds into its unique three-dimensional structure, which in turn determines its specific function. Differences in amino acid sequences between enzymes result in different tertiary structures and different functional properties. Secondary structures alone don't account for functional specificity.
