Statement B: Enzymes exhibiting tertiary structure lack secondary and primary structures. O Both statements are incorrect O Only statement A is correct O Only statement B is correct Both statements are correct​

Answer 1

The correct option is selected as follows: Only statement A is correct.

Statement A: All enzymes are proteinaceous in nature.

• Almost all of the enzymes are proteins.
• Thus, this statement is correct.

Statement B: Enzymes exhibiting tertiary structure lack secondary and primary structures.

• Enzymes have all three structures which are present in proteins, primary, secondary, and tertiary.
• The amino acid sequence in enzymes comprises the primary structure.
• The active site of an enzyme is one of the pockets made when the backbone of the protein chain folds upon itself.
• Thus, this statement is incorrect.
