Number of polypeptide chain present in a molecule of antibody
1 2
2 4
3 6
4 8
Explanation:
Each antibody molecule has two light chains and two heavy chains. The heavy chains (H-chains) are structurally and antigenically distinct and form different antibodies, represented by \(\mathrm{H}_{2} \mathrm{~L}_{2}\)

Antigenic determinants of an antigen recognized by antibodies are
1 Paratopes
2 Epitopes
3 Isotopes
4 Non-determinants
Explanation:
Antigen have determinants called epitopes. Epitopes are molecular shapes recognised by antibodies, which recognise 1 epitope rather than the whole antigen.

Antibodies are produced by
1 Histiocytes
2 Mast cells
3 Plasma cells
4 Fibroblasts
Explanation:
Plasma cells, also called plasmaB cells, plasmocytes, plasmacytes, or effector B cells, are white blood cells that secrete large volumes of antibodies. They are transported by the blood plasma and the lymphatic system.

Which of the following is not present in human milk
1 Nutrients
2 Fat
3 \(\operatorname{IgM}\)
4 \(\operatorname{IgA}\)
Explanation:
Colostrum contains more minerals and protein, but less sugar and fat. Antibodies are demonstrable in colostrum; immunoglobulin A may protect the newborn against enteric pathogens.
