Lysosomes are described as which of the following?

Lysosomes are membrane-bound vesicles that contain digestive enzymes. Their interior is acidic, which optimizes these acid hydrolases to break down proteins, nucleic acids, and other macromolecules from outside the cell or from damaged organelles. The lysosome’s membrane protects the rest of the cell from these potent enzymes. They are formed from the Golgi apparatus and fuse with endosomes or autophagosomes to degrade their contents. This makes them best described as membrane vesicles that contain digestive enzymes. The other options don’t fit because energy production is done by mitochondria (and chloroplasts in plants), ribosome assembly occurs in the nucleolus, and calcium storage is primarily handled by other organelles like the endoplasmic reticulum and mitochondria.
