Peroxisome
B
Lysosome
C
Mitochondrion
D
Golgi apparatus
Verified step by step guidance1
Identify the function described in the question: the organelle contains acid hydrolase digestive enzymes that break down macromolecules as part of lysosomal and degradation pathways.
Recall that acid hydrolases are enzymes that function optimally at acidic pH and are responsible for degrading various biomolecules such as proteins, lipids, carbohydrates, and nucleic acids.
Understand that lysosomes are membrane-bound organelles in eukaryotic cells that contain these acid hydrolase enzymes and serve as the primary site for intracellular digestion and recycling of cellular components.
Compare the other options: peroxisomes are involved in lipid metabolism and detoxification, mitochondria generate ATP through cellular respiration, and the Golgi apparatus modifies and sorts proteins but does not contain acid hydrolases for degradation.
Conclude that the organelle described is the lysosome, as it matches the function of containing acid hydrolase digestive enzymes for breaking down macromolecules.
