1. lysosomes
Explanation:
Lysosomes are a membrane-bound organelles with acidic interior that enables the function of hydrolytic enzymes. So, the main role of lysosomes is degradation of macromolecules. Low pH (about 5) is suitable for the action of enzymes involved in hydrolysis (hydrolases) and there are about 50 of them inside the lysosome. Beside macromolecules, lysosomes degrade organelles, but also can digest themselves via autophagy (e.g. when cell is under stress).
Lysosomes are also involved in plasma membrane repair, defend agains pathogens (macrophages), cell signaling, metabolism etc.
