Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A cell organelle that breaks down lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell.
A
vesicle
B
vacuole
C
lysosome
D
chloroplast
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 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-3: -The organelle called ‘endoplasmic reticulum’ occurs in both plants and animals and is a very important manufacturing site for lipids (fats) and many proteins.

Detailed explanation-4: -One of the key organelles involved in digestion and waste removal is the lysosome. Lysosomes are organelles that contain digestive enzymes. They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.

Detailed explanation-5: -Lysosomes are acidic organelles containing at least 50 different hydrolases that degrade a wide variety of macromolecules, including DNA, proteins, carbohydrates, and lipids delivered via autophagy and other endocytic pathways.
