In eukaryotic cells, which organelle is primarily responsible for eliminating intracellular waste by degrading macromolecules and damaged organelles using hydrolytic enzymes?
A
Golgi apparatus
B
Mitochondrion
C
Nucleus
D
Lysosome
Verified step by step guidance1
Understand the function of each organelle listed: The Golgi apparatus modifies, sorts, and packages proteins; the mitochondrion generates ATP through cellular respiration; the nucleus stores genetic information.
Recall that the organelle responsible for degrading macromolecules and damaged organelles contains hydrolytic enzymes capable of breaking down various biomolecules.
Identify that lysosomes are membrane-bound organelles containing these hydrolytic enzymes, which digest intracellular waste and recycle cellular components.
Recognize that lysosomes perform autophagy, a process where damaged organelles are enclosed and degraded to maintain cellular health.
Conclude that among the options, the lysosome is the organelle primarily responsible for eliminating intracellular waste by degradation.
