Q:

Which one of the following cell organelles mainly functions as storehouse of digestive enzymes?

A) Desmosome B) Ribosome
C) Lysosome D) Vacuoles
 
Answer & Explanation Answer: C) Lysosome

Explanation:

Lysosome is found in nearly all types of eukaryotic cells (cells with a clearly defined nucleus) and is responsible for the digestion of macromolecules, old cell parts, and microorganisms. Each lysosome is surrounded by a membrane that maintains an acidic environment within the interior via a proton pump. Lysosomes contain a wide variety of hydrolytic enzymes (acid hydrolases) that break down macromolecules such as nucleic acids, proteins, and polysaccharides. So, they are known as storehouse of digestive enzymes.
