C
Lysosome
D
Mitochondrion
Verified step by step guidance1
Identify the function of each organelle listed in the problem to understand their roles in the cell.
Recall that the Golgi apparatus is primarily involved in modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.
Understand that the rough endoplasmic reticulum (RER) is mainly responsible for synthesizing proteins destined for membranes or secretion, characterized by ribosomes on its surface.
Recognize that mitochondria are the powerhouses of the cell, generating ATP through cellular respiration, and are not primarily involved in waste processing or degradation.
Focus on lysosomes, which contain hydrolytic enzymes that break down cellular waste, damaged organelles, and macromolecules, making them the main organelle for storage and processing of cellular waste and materials destined for degradation.
