Why is the cell's compartmental structure particularly important for the function of peroxisomes?

  • A: To provide a stable environment for enzyme synthesis.
  • B: To store excess oxygen for cellular respiration.
  • C: To sequester toxic hydrogen peroxide (H2O2) and the enzymes that produce/dispose of it, preventing damage to other cellular components.
  • D: To regulate the cell's overall energy metabolism.

Explanation

Peroxisomes produce hydrogen peroxide H2O2 as a by-product, which is toxic to the cell. The single membrane of the peroxisome ensures that this toxic compound and the enzymes involved in its production and conversion to water are safely sequestered, preventing damage to other cellular components.
