Which of the following is responsible for phagocytosis?: (A) C5a, (B) C3a, (C) C3b, (D) TNF-a
Answer is C. The process of phagocytosis is fuher enhanced when microorganisms are coated with specific proteins, opsonins from the serum. Opsonins establish a bond between bacteria and bacteria and the membrane of the phagocytic cell. C3b is opsonin generated by activation of cothe complement pathway.
