The correct answer is
Enzymes digest the cell’s own components

Lysosome Bursting Consequences

Lysosomes are cellular organelles containing powerful hydrolytic enzymes designed to break down waste materials and cellular debris.

Mechanism of Lysosome Bursting

When a lysosome encounters damage or specific cellular signals, its membrane can rupture. This rupture releases the potent digestive enzymes contained within the lysosome directly into the cell's cytoplasm.

Enzyme Action on Cell Components

  • The released hydrolytic enzymes are non-specific and function optimally in the acidic environment within the lysosome.
  • Upon release into the neutral pH of the cytoplasm, these enzymes can still remain active to some extent.
  • These active enzymes begin to digest various components of the cell itself, including proteins, carbohydrates, lipids, and nucleic acids.
  • This process is often referred to as autolysis.

Conclusion

Therefore, when lysosomes burst, the released enzymes digest the cell’s own components, leading to cell damage or death.

The correct option is that Enzymes digest the cell’s own components.
