Which membrane-bound organelles are primarily responsible for intracellular digestion, containing a variety of hydrolytic enzymes such as proteases, nucleases, and lipases, and function in breaking down cellular waste, pathogens, and damaged organelles?
| 1. | Peroxisomes – contain oxidative enzymes for detoxification and fatty acid breakdown |
| 2. | Lysosomes – contain acidic hydrolases for degradation of biomolecules |
| 3. | Golgi apparatus – modifies, sorts, and packages proteins for secretion |
| 4. | Endoplasmic reticulum – involved in protein synthesis and lipid metabolism |
