D
Mitochondrion
Verified step by step guidance1
Identify the function described in the problem: breaking down macromolecules during intracellular degradation using acid hydrolases (digestive enzymes).
Recall that acid hydrolases are enzymes that function optimally at acidic pH and are involved in digesting various biomolecules such as proteins, lipids, and nucleic acids.
Consider the organelles listed: Peroxisome, Lysosome, Golgi apparatus, and Mitochondrion, and their primary functions in the cell.
Recognize that lysosomes are membrane-bound organelles containing acid hydrolases and are specialized for intracellular digestion and recycling of cellular components.
Conclude that the organelle responsible for this function is the lysosome, as it contains the acid hydrolases needed for breaking down macromolecules inside the cell.
