Question

The cell walls of many gram positive bacteria can be easily destroyed by the enzyme known as
A.lipase
B. lysozyme
C. pectinase
D. peroxidase

Answer 1

The cell walls of many gram positive bacteria can be easily destroyed by the enzyme known as B. lysozyme

Answer 2

Cell walls of many gram-positive bacteria can be easily destroyed by the enzyme Lysozyme (Option - B)

• The Cell wall of gram-positive bacteria consists of multiple layers consisting of techoic acid, Peptidoglycans, proteins, and polysaccharides.
• pectin is mostly present in the plant cell walls, therefore Pectinase can be used to disrupt plant cell walls.
• Lysozyme is able to disrupt the peptidoglycan - NAG (N - acetylglucosamine)-NAM(N - acetyl muramic acid) crosslinking and destroy the cell wall of bacteria leading to the killing of bacteria.
• Gram-negative bacteria do not consist of Peptidoglycan.
• Peroxidase enzyme is used to destroy the Reactive Oxygen species.
