Question

Arrange the following steps of phagocytosis in sequence:
(A). Phagosome fuses with lysosome
(B). Bacterium is ingested, forming phagosome
(C). Bacterium is killed by lysosomal enzymes
(D). Bacterium becomes attached to pseudopodia
Choose the correct answer from the options given below:

• A. (D), (B), (A), (C)
• B. (A), (C), (B), (D)
• C. (B), (A), (D), (C)
• D. (C), (B), (D), (A)

Hint:

Understanding the steps of phagocytosis is crucial in the study of the immune response

Answer 1

The Correct Option is A

The sequence of phagocytosis starts with the bacterium becoming attached to the pseudopodia followed by ingestion phagosome-lysosome fusion and finally bacterial destruction by lysosomal enzymes
