Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organelle breaks down food into particles the cell can use?
A
Golgi apparatus
B
endoplasmic reticulum
C
mitochondrion
D
lysosome
Explanation: 

Detailed explanation-1: -Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself.

Detailed explanation-2: -Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell.

Detailed explanation-3: -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.

Detailed explanation-4: -Lysosomes contain a wide variety of hydrolytic enzymes (acid hydrolases) that break down macromolecules such as nucleic acids, proteins, and polysaccharides.

Detailed explanation-5: -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.
