Question

Lysosomes are considered as 'suicidal bags' because of

• A. Catabolic activities
• B. Phagocytic activities
• C. Lytic activites
• D. All of the above

Answer 1

The correct option is D All of the above

Lysosome is essentially a sphere of lipoprotein membrane containing hydrolytic enzymes. The membrane insulates the enzymes from the rest of the cell. If the plasma membrane get rupture or the pH of the cell get decrease then the enzymes are released from the lysosome and lyse or digest the cell contents and, hence, lysosomes are sometimes called as suicidal bags. The process of digestion of the lysosomes is known as phagocytosis. The lysosomes digest the complex molecules by breaking it into simpler molecules. The process is known as catabolism.

Thus, the correct answer is option D.
