Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organelles release chemicals that break down large food particles into smaller ones?
A
vacuoles
B
lysosmes
C
Golgi bodies
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: -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.

Detailed explanation-3: -Lysosomes contain a wide variety of hydrolytic enzymes (acid hydrolases) that break down macromolecules such as nucleic acids, proteins, and polysaccharides.

Detailed explanation-4: -Lysosomes are formed by the fusion of vesicles that have budded off from the trans-Golgi.

Detailed explanation-5: -“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.
