Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the function of a lysosome?
A
To digest macromolecules and cellular waste
B
To act as the respiratory system of the cell.
C
To house genetic material.
D
To sort proteins from the rough ER and ribosomes.
Explanation: 

Detailed explanation-1: -Lysosomes dispose and recycle extracellular or intracellular macromolecules by fusing with endosomes or autophagosomes through specific waste clearance processes such as chaperone-mediated autophagy or microautophagy.

Detailed explanation-2: -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-3: -“Lysosomes are sphere-shaped sacs filled with hydrolytic enzymes that have the capability to break down many types of biomolecules.” In other words, lysosomes are membranous organelles whose specific function is to breakdown cellular wastes and debris by engulfing it with hydrolytic enzymes.

Detailed explanation-4: -As most high schoolers learn, the lysosome carries out waste disposal and recycling. In a process known as autophagy (meaning “self-eating”), it takes in old cellular components and unneeded large molecules, such as proteins, nucleic acids and sugars, and digests them with the help of enzymes and acids.
