Verified step by step guidance
1
Understand the function of peroxisomes: Peroxisomes are small, membrane-bound organelles that contain enzymes involved in various metabolic reactions, including the breakdown of fatty acids and the detoxification of harmful substances.
Recognize the metabolic process: One of the key reactions that occur in peroxisomes is the breakdown of long-chain fatty acids through beta-oxidation, which generates hydrogen peroxide (H₂O₂) as a byproduct.
Identify the role of catalase: Peroxisomes contain the enzyme catalase, which converts hydrogen peroxide, a potentially harmful byproduct, into water and oxygen, thereby neutralizing its toxicity.
Differentiate from other organelles: Unlike peroxisomes, the Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids, while mitochondria are primarily responsible for energy production through cellular respiration, and lysosomes are involved in digestion and waste removal.
Conclude the identification: Based on the metabolic processes and the production of hydrogen peroxide, peroxisomes are the organelles responsible for producing hydrogen peroxide as a byproduct.
