Question

Choose the correct sequence in which lysosomes kill pathogens.

i. Releases debris
ii. Fuses with the pathogen
iii. Enzymes digest pathogen
iv. Phagosome formation

• A. ii $\to$ iv $\to$ i $\to$ iii
• B. ii $\to$ iv $\to$ iii $\to$ i
• C. ii $\to$ i $\to$ iii $\to$ iv
• D. iii $\to$ iv $\to$ ii $\to$ i

Answer 1

The correct option is B ii $\to$ iv $\to$ iii $\to$ i

Lysosome is known as the suicidal bag of the cell. When a lysosome tries to kill a pathogen, it first fuses with it. This fusion forms a structure called phagosome. Inside the phagosome, the digestive enzymes of the lysosome digest the pathogen and then release the debris out of it.
