Trypsin is an enzyme. The pancreas adds a collection of protein-cutting enzymes, with trypsin playing the central role, that chop the protein chains into pieces just a few amino acids long. Then, enzymes on the surfaces of intestinal cells and inside the cells chop them into amino acids, ready for use throughout the body. Trypsin uses a special serine amino acid in its protein-cutting reaction, and is consequently known as a serine protease.
Correct Option: C

Sand fly insects spread Kala-azar. Kala-azar is a chronic and potentially fatal parasitic disease of the viscera (the internal organs, particularly the liver, spleen, bone marrow and lymph nodes) due to infection by the parasite called Leishmania donovani. Leishmania donovani, the agent of kala-azar , is transmitted by sandfly bites.

Blood plasma cells form 55-60% by volume of blood. Antibodies and some other substances such as lysozyme and properdin always occur in the plasma. They serve to destroy bacteria, viruses and toxic substances that may enter into the blood from outside or from body tissues.
