Solution
The correct option is B Lysozyme
When we ingest food, the saliva produced by the salivary glands mix with the food. Saliva consists of water, electrolytes (salts), mucus, and the enzymes salivary amylase and lysozyme. The electrolytes are essential for the stability of the enzymes. The mucus helps in lubrication of the food that is chewed and eventually swallowed. The enzyme salivary amylase catalyses the digestion of starch to maltose. The enzyme lysozyme makes holes in the cell walls of the bacteria that we ingest with food and thus kills them.
