In eukaryotic cells, which organelle is primarily responsible for detoxifying harmful substances such as hydrogen peroxide via enzymes like catalase?
A
Golgi apparatus
B
Lysosome
C
Mitochondrion
D
Peroxisome
Verified step by step guidance1
Identify the function described in the problem: detoxification of harmful substances such as hydrogen peroxide.
Recall that hydrogen peroxide (H2O2) is a reactive oxygen species that can be harmful to cells if not broken down.
Understand that the enzyme catalase is responsible for converting hydrogen peroxide into water and oxygen, thereby neutralizing its toxicity.
Recognize that the organelle containing catalase and specialized in detoxifying hydrogen peroxide is the peroxisome.
Confirm that other organelles listed (Golgi apparatus, lysosome, mitochondrion) have different primary functions and are not mainly involved in detoxifying hydrogen peroxide.
