The entrance of a microbe into an individual's vascular space has initiated opsonization. How will the health care provider explain this process critical in stopping the infiltration of the microbe through opsonization? Opsonization:
A) Stimulates B cells by helper T cells
B) Coats a microbe to activate phagocytosis recognition
C) Releases proteins that stimulate cell production by the bone marrow
D) Involves lysis of intracellular microbes by cytotoxic T cells
Ans: B
Feedback:
The coating of particles, such as microbes, is called opsonization, and the coating materials are called opsonins. The opsonin bound to the microbe then activates the phagocyte after attachment to a complementary receptor on the phagocyte. Opsonization does not involve stimulation by T cells, stimulation of the bone marrow, or the lysis of microbes by cytotoxic T cells.
