Which organelles are filled with powerful enzymes that digest worn-out cell components and destroy microbes?
A) peroxisomes
B) lysosomes
C) mitochondria
D) smooth endoplasmic reticulum
Powerful Enzymes
Biomolecules that significantly speed up the rate of virtually all of the chemical reactions that take place within cells.
Worn-out Cell Components
Describes cellular components that have become dysfunctional or degraded after their normal lifespan or use within the cell, needing recycling or removal.
Smooth Endoplasmic Reticulum
A network of tubular membranes within cells, involved in lipid synthesis, metabolism, and calcium ion storage, lacking ribosomes.
- Recognize the roles of different organelles in cellular processes such as protein synthesis, digestion of cell components, and DNA replication.

Final Answer :
B
Explanation :
Lysosomes are organelles filled with powerful enzymes that digest worn-out cell components and destroy microbes. Peroxisomes contain enzymes that break down fatty acids and detoxify harmful substances. Mitochondria are responsible for producing energy through cellular respiration. Smooth endoplasmic reticulum is involved in lipid synthesis and detoxification of drugs and poisons, but it does not have enzymes for digesting worn-out cell components or destroying microbes.
