Question

Which of the following organism is not correctly matched with its cell wall degrading enzyme?

• A. Fungi - chitinase
• B. Bacteria - lysozyme
• C. Plant cells - cellulase
• D. Algae - methylase

Answer 1

Answer: (D)

Algae - methylase

• The main component of the fungal cell wall is chitin. Hence chitinase enzyme is used to degrade the cell walls of fungal cells.
• Lysozyme inactivates bacteria by hydrolysis of glucosidic linkages in the peptidoglycan of cell walls.
  
• Cellulase enzymes are used to break down the cellulose of plant cells.
  
• The algal cell wall is made up of cellulose and thus can be degraded by the enzyme cellulase. Whereas, methylase is the enzyme that adds a methyl group to the adenine or cytosine residues of DNA or RNA.

So the correct answer is option D.
