Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which biomolecule is found in lysosomes to help them digest and break down materials?
A
carbohydrate
B
lipid
C
nucleic acid
D
protein
Explanation: 

Detailed explanation-1: -Lysosomes contain a wide variety of hydrolytic enzymes (acid hydrolases) that break down macromolecules such as nucleic acids, proteins, and polysaccharides.

Detailed explanation-2: -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-3: -Lysosomes are spherical vesicles which contain hydrolytic enzymes that can break down virtually all biomolecules (e.g., peptides, nucleic acids, carbohydrates, and lipids).

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.

Detailed explanation-5: -Those enzymes are called hydrolytic enzymes, and they break down large molecules into small molecules. For example, large proteins into amino acids, or large carbohydrates into simple sugars, or large lipids into single fatty acids.
