SSC Selection Post 2022 PYQ — Question 35

The correct answer is option 4 i.e. Lactoferrin, lactoperoxidase, and lysozyme.

Lactoferrin is an iron-binding protein that deprives bacteria of iron, an essential nutrient for their growth, thus inhibiting their proliferation.

Lactoperoxidase works as part of a system (with hydrogen peroxide and thiocyanate) to produce compounds that have strong antibacterial effects.

Lysozyme acts by breaking down the cell walls of certain bacteria, leading to their destruction.
