Which organelle breaks downs material and waste products?
A
ER
B
golgi bodies
C
ribosomes
D
lysosomes
Explanation: 

Detailed explanation-1: -Lysosomes break down cellular waste products, fats, carbohydrates, proteins, and other macromolecules into simple compounds, which are then transferred back into the cytoplasm as new cell-building materials.

Detailed explanation-2: -Lysosomes have powerful enzymes and acids to digest and recycle cell materials. Credit: Judith Stoffer. Proteins aren’t the only type of cellular waste. Cells also have to recycle compartments called organelles when they become old and worn out.

Detailed explanation-3: -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.

Detailed explanation-4: -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.

Detailed explanation-5: -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.
