Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organelle contains enzymes that break down damaged cell parts?
A
centriole
B
lysosomes
C
vacuole
D
mitochondria
Explanation: 

Detailed explanation-1: -Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers-proteins, nucleic acids, carbohydrates, and lipids.

Detailed explanation-2: -Lysosomes are organelles that contain digestive enzymes (acid hydrolases). They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.

Detailed explanation-3: -Lysosomes are membrane-bound organelles found in every eukaryotic cell. They are widely known as terminal catabolic stations that rid cells of waste products and scavenge metabolic building blocks that sustain essential biosynthetic reactions during starvation.

Detailed explanation-4: -Lysosomes break down macromolecules into their constituent parts, which are then recycled. These membrane-bound organelles contain a variety of enzymes called hydrolases that can digest proteins, nucleic acids, lipids, and complex sugars. The lumen of a lysosome is more acidic than the cytoplasm.

Detailed explanation-5: -Answer and Explanation: The answer is B lysosome. Lysosomes are membrane-bound organelles that have enzymes that digest damaged, worn down, or excessive organelles.
