Question

As they release hydrolase that digest old and damaged cells, the term suicide bags is aptly used by cell biologists for
A. Golgi bodies
B. Lysosomes
C. Glyoxysomes
D. Peroxisomes

Answer 1

Hint: The lysosome is also called suicide bags because they have autolytic or autophagic properties (breakdown of its own cell) and when it digests something other than its own cell it is called heterolysis or heterophagy.

Complete answer:
In this question, we have asked about the suicidal bag. The lysosome is called a suicidal bag. Lysosome is a membrane bound cell organelle that contains digestive enzymes, these enzymes are called hydrolytic enzymes. Lysosomes digest the food materials present in the cell and remove the foreign bodies, toxic molecules, and debris. It is also called recycling centers because they break down the dead and defective cells and remove them from the cell. Lysosome also participates in apoptosis (programmed cell death).
When lysosomal membrane rupture, hydrolases and other enzymes reach cytosol and degrade the vital components like organelles, plasma membrane and nucleus, which leads to cell death of the cell. In this case the cell died due to its own enzyme, so this process is cell suicide and it occur because of lysosomes, so lysosome is also known as suicide bag by biologists.

So, the correct option is B. Lysosome.

Note:
The data can vary because new hotspots are declared. According to new data the total no. of biological hotspots are 36 as two more hotspots are added. But according to old data 34 is the correct answer. If we have 36 in the options, then we'll mark 36.The lysosome contains a very acidic enzyme. So, it has a membrane around to protect the cell from the acidic medium and digestive enzymes. When the lysosomal membrane ruptures, autolysis or suicide of the cell occur.
