The third step of phagocytosis is
A
Chemotaxis
B
Lysosomal fusion
C
Binding
D
Excretion
E
Engulfment
Explanation: 

Detailed explanation-1: -The process of phagocytosis involves several phases: i) detection of the particle to be ingested, ii) activation of the internalization process, iii) formation of a specialized vacuole called phagosome, and iv) maturation of the phagosome to transform it into a phagolysosome.

Detailed explanation-2: -This is followed by fusion with lysosomes, acidification of the phagosome, and degradation of the target. The most widely-studied example of phagocytosis in-volves Fcg receptors, which recognize particles coated with immunoglobulin G (IgG) (6, 7).
