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 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-4: -Two classes of proteins are essential for the function of lysosomes: soluble lysosomal hydrolases (also referred to as acid hydrolases) and integral lysosomal membrane proteins (LMPs).

Detailed explanation-5: -When food is eaten or absorbed by the cell, the lysosome releases its enzymes to break down complex molecules including sugars and proteins into usable energy needed by the cell to survive. If no food is provided, the lysosome’s enzymes digest other organelles within the cell in order to obtain the necessary nutrients.
