Difficulty: EasyCell Biology, Genetics, and Evolution

Which of the following cell organelles contains powerful hydrolytic enzymes capable of digesting cellular waste and is commonly referred to as the 'suicide bag' of the cell?

  1. LysosomeAnswer
  2. B
    Ribosome
  3. C
    Golgi Apparatus
  4. D
    Endoplasmic Reticulum

Answer

The organelle referred to as the 'suicide bag' of the cell is the Lysosome.
Lysosomes are membrane-enclosed organelles containing hydrolytic enzymes produced by the rough endoplasmic reticulum and packaged by the Golgi apparatus. They break down cellular macromolecules, damaged organelles, and engulfed pathogens. In injured or dying cells, lysosomal membranes disintegrate, causing autolysis (self-digestion), which is why they are called 'suicide bags'.

Step-by-Step Solution

1
Identify the primary function described in the question stem
The question specifies intracellular digestion using hydrolytic enzymes and self-destruction capability.
Lysosomes store digestive enzymes like lipases, proteases, and nucleases working at acidic pH.
2
Match the organelle function with known biological terminology
Lysosomes perform autolysis when the cell is damaged, earning the terminology 'suicide bags'.
Bursting of lysosomes releases hydrolytic enzymes that digest their own cellular components.
