Which organelle contains acid hydrolases (digestive enzymes) that function in intracellular degradation?
A
Mitochondrion
B
Lysosome
C
Golgi apparatus
D
Peroxisome
Verified step by step guidance1
Understand the function of each organelle listed: Mitochondrion, Lysosome, Golgi apparatus, and Peroxisome.
Recall that acid hydrolases are enzymes that break down biomolecules in an acidic environment, which is characteristic of lysosomes.
Recognize that lysosomes are membrane-bound organelles containing these acid hydrolases, responsible for intracellular digestion and recycling of cellular components.
Note that mitochondria are involved in energy production, Golgi apparatus in protein modification and sorting, and peroxisomes in lipid metabolism and detoxification, none of which primarily contain acid hydrolases for degradation.
Conclude that the organelle containing acid hydrolases for intracellular degradation is the lysosome.
