Homework Answers
Ans. Correct option- B. Opsonization. Opsonization is the process by which the immune system marks a pathogen (an antigen) for phagocytosis. During the process, the opsonin (antibodies) bind to the specific PAMPs of pathogen’s cell surface, thus marking the pathogen-opsonin complex for phagocytosis by phagocytic immune cells.
# Option A- Incorrect. Chemotaxis is the process of movement of a cell towards a specific chemical stimulus. The term is not equivalent to opsonization.
# Option C- Incorrect. Degranulation is release of contents from the intracellular granules of granulocytes. The granular content facilitates immune responses, but the term is not exclusive for marking the phagocytosis of a pathogen by immune system.
# Option- D. Incorrect. Exocytosis is the process of release of some cellular contents outside the cell by packing it in vesicles.

QUESTION 32 Which process involves the recognition of microbial molecules called pathogen-associated molecular pattern, such as LPS, lipoteichoic acids, peptidoglycan fragments, the sugar mannose, and flagellin, molecules not normally associated with human cells by means of endocytic pattern-recognition receptors on the surface of phagocytes? Enhanced attachment of microbes to phagocytes (opsonization). The role of LPS in bacterial pathogenicity. How bacteria commonly resist phagocytosis. Unenhanced attachment of microbes to phagocytes.

Alpaca Conventional antibody Alpaca heavy- chain antibody Nanobody/ VH CH1 VH Single domain antibodies are a type of antibody produced naturally by llamas and other camelids, which consist of only a single monomeric heavy chain or light chain but nonetheless can achieve equal binding affinity to antigens as conventional antibodies. A new product, called nanobodies, can be derived from single domain antibodies as depicted in the diagram. While their purpose in these animals is currently unclear, there is large commercial...
